Summary of the various useful resources ______________________________________________________________________ 11.. AAddmmiinniissttrraattiivviiaa 11..11.. IInnttrroodduuccttiioonn This document covers the things you need to successfully work with information containing cyrillic text (mostly Russian) under Linux. Although this document assumes your using Linux as an operating system, most of information presented is equally applicable to many other Unix flavors. I shall try to keep the distinction as visible as possible. There are a number of popular Linux distributions. As an example system I describe the RedHat 4.1 Linux (Vanderbildt) - the one I am personally using. Nevertheless, I shall try to highlight the differences, if they exist, in other popular distributions, such as Debian GNU/Linux and Slackware Linux. Since such setup directly modifies and extends the Operating System, you should understand, what you are doing. Even though I tried to keep things as easy as possible, having some experience with a given piece of software is an advantage. I am not going to describe what the X Window System is or how to typeset the documents with TeX and LaTeX, or how to install printer in Linux. Those issues are covered in other documents. For the same reason, in most cases I describe a system-wide setup, by default requiring _r_o_o_t privileges. Still, if there is a possibility for user-level setup, I'll try to mention it. NNOOTTEE:: The X Window System, TeX and other Linux components are complex systems with a sofisticated configuration. If you do something wrong, you can not only fail with Russian setup, but to break the component as well, if not the entire system. This is not to scare you off, but merely to make you understand the seriousness of the process and be careful. Preliminary backup of the config files is hhiigghhllyy recommended. Having a guru around is also advantageous. 11..22..

CChhaarraacctteerrss aanndd ccooddeesseettss In order to understand and print characters of various languages, the system and software should be able to distinguish them from other characters. That is, each unique character must have a unique representation inside the operating system, or the particular software package. Such collection of all unique characters, that the system is able to represent at once, is called a _c_o_d_e_s_e_t. At the time of the most operating system's creation, nobody cared about software being multilingual. Therefore, the most popular codeset was (and actually is) an _A_S_C_I_I (American Standard Code for Information Interchange). The _s_t_a_n_d_a_r_d _A_S_C_I_I (aka 7-bit ASCII) comprises 128 unique codes. Some of them ASCII defines as real printable characters, and some are so- called _c_o_n_t_r_o_l _c_h_a_r_a_c_t_e_r_s, which had special meanings in the old communication protocols. Each element of the set is identified by an integer _c_h_a_r_a_c_t_e_r _c_o_d_e (0-127). The subset of printable characters represents those found on the typewriter's keyboard with some minor additions. Each character occupies 7 least significant bits of a byte, whereas the most significant one was used for control purposes (say, transmission control in old communication packages). The 7-bit ASCII concept was extended by 8-bit ASCII (aka _e_x_t_e_n_d_e_d _A_S_C_I_I). In this codeset, the characters' codes' range is 0-255. The lower half (0-127) is pure ASCII, whereas the upper one contains 127 more characters. Since this codeset is backward compatible with the ASCII (character still occupies 8 bit, the codes correspond the old ASCII), this codeset gained wide popularity. The 8-bit ASCII doesn't define the contents of the upper half of the codeset. Therefore the ISO organization took the responsibility of defining a family of standards known as _I_S_O _8_8_5_9_-_X family. It is a collection of 8-bit codesets, where the lower half of each codeset (characters with codes 0-127) matches the ASCII and the upper parts define characters for various languages. For example, the following codesets are defined: +o 8859-1 - Europe, Latin America (also known as _L_a_t_i_n _1) +o 8859-2 - Eastern Europe +o 8859-5 - Cyrillic +o 8859-8 - Hebrew In Latin 1, the upper half of the table defines various characters which are not part of the English alphabet, but are present in various european languages (german umlauts, french accentes etc). Another popular extended ASCII implementation is so-called _I_B_M _c_o_d_e_p_a_g_e (named after some computer company, that developed this codeset for it's infamous personal computers). This one contains pseudo-graphic characters in the upper half. Software, that doesn't make any assumptions about the 8-th bit of the ASCII data is called _8_-_b_i_t _c_l_e_a_n. Some older programs, designed with 7-bit ASCII in mind are not 8-bit clean and may work incorrectly with your extended ASCII data. Most of packages, however, are able to deal with the extended ASCII by default, or require some very basic setup. NNOOTTEE:: before posting the question _"_I _d_i_d _a_l_l _s_e_t_u_p _r_i_g_h_t_, _b_u_t _I _c_a_n_n_o_t _e_n_t_e_r_/_v_i_e_w _C_y_r_i_l_l_i_c _c_h_a_r_a_c_t_e_r_s_!_", please consult the section ``'' for the notes on the program, you are using. For information about making your software 8-bit clean, see section ``''. Since on most systems character occupies 8 bits, there is no way to extend ASCII more and more. The way to implement new symbols in ASCII- based codesets is creation of other extended ASCII implementations. This is the way, the Cyrillic ASCII set is implemented. We already mentioned _I_S_O _8_8_5_9_-_5 standard as the one defining the Cyrillic codeset. But as it often happens to the standards, this one was developed without taking into account the real practices in the former USSR. Therefore, one thing that standard really achieved was another degree of confusion. I wouldn't say that _I_S_O _8_8_5_9_-_5 is widely used anywhere. Other standards for Cyrillic include the so-called _A_l_t codeset and _M_i_c_r_o_s_o_f_t _C_P_1_2_5_1 codepage. The former one was developed by (who?) for MS-DOS quite a while ago. Back then, there was not very buzz yet about internetworking, so the intention was to make it as compatible as possible with the IBM standard. Therefore the Alt codeset is effectively the same IBM codepage, where all specific European characters in the upper half were replaced with the Cyrillic ones, leaving the pseudographic ones. Therefore, it didn't screw the text windowing facilities and provided Cyrillic characters as well. The _A_l_t standard is still alive and extremely popular in MS-DOS. _M_i_c_r_o_s_o_f_t _C_P_1_2_5_1 _c_o_d_e_p_a_g_e is just an attempt of Microsoft to come up with the new standard for Cyrillic codeset in Windows. As far as I know, it is not compatible with anything else (not very surprizing, huh?) And finally there is _K_O_I_8_-_R. This one is also quite old, but it was designed wisely and nowadays the design points of it look really useful. Again, it is compatible with ASCII, and the Cyrillic characters are located in the upper half. But the main design point of _K_O_I_8_-_R is that the Cyrillic characters' positions must correspond to the English characters with the same phonetics. Namely, if we set the eighth bit of the English character 'a', we'll get the Cyrillic 'a'. This means that, given the Cyrillic text written in KOI8-R, we can strip the eighth bit of each character _a_n_d _w_e _s_t_i_l_l _g_e_t _a _r_e_a_d_a_b_l_e _t_e_x_t_, _a_l_t_h_o_u_g_h _w_r_i_t_t_e_n _w_i_t_h _E_n_g_l_i_s_h _c_h_a_r_a_c_t_e_r_s_! This is very important now, since there are many mailers on the Internet, that just strip the eighth bit silently, being sure that every single soul on the face of the Earth speaks English. Not surprisingly, _K_O_I_8_-_R quickly became a de-facto standard for Cyrillic on the Internet. Andrew A. Chernov did a tremendous amount of work to make a standard in this area. He is an author of RFC 1489 (_"_R_e_g_i_s_t_r_a_t_i_o_n _o_f _a _C_y_r_i_l_l_i_c _C_h_a_r_a_c_t_e_r _S_e_t_"). These two standards differ only in positions of the cyrillic characters in the table (that is in cyrillic character codes). The principal difference is that the Alt codeset is used by MS-DOS users only, whereas KOI8-R is used in Unix, as well as in MS-DOS (though in the latter KOI8-R is much less popular). Since we are doing the right thing (namely working in the Unix operating system), we shall focuse mostly on KOI8-R. As for the ISO standard, it is more popular in Europe and the US as a standard for Cyrillic. The leader in Russia is definitely KOI8-R. There are other standards, which are different from ASCII and much more flexible. _U_n_i_c_o_d_e is most known. However, they are not implemented as good as the basic ones in Unix in general and Linux in particular. Therefore, I am not describing them here. 33.. PPrreeppaarriinngg yyoouurr eennvviirroonnmmeenntt Before we start customizing various parts of the system functionality, we have to set up a couple basic things. Most of tools described below assume that there are Cyrillic fonts available and a user is able to input Cyrillic characters. To make it true we have to configure the environment to provide both fonts and input facility for Cyrillic. There are effectively two interface models supported by Linux. One is the text mode, and the other one is the graphic mode, provided by the X Window System. Both require different setup, which will be described below. 33..11.. TTeexxtt mmooddee sseettuupp Generally, the text mode setup is the easiest way to show and input Cyrillic characters. There is one significant complication, however: the text mode fonts and keyboard layout manipulations depend on terminal driver implementation. Therefore, there is no portable way to achieve the goal across different systems. Right now, I describe the way to deal with the Linux console driver. Thus, if you have another system, don't expect it to work for you. Instead, consult your terminal driver manual. Nevertheless, send me any information you find, so I'll be able to include it in further versions of this document. 33..11..11.. LLiinnuuxx CCoonnssoollee The Linux console driver is quite a flexible piece of software. It is capable of changing fonts as well as keyboard layouts. To achieve it, you'll need the kbd package. Both RedHat and Slackware install kbd as part of a system. The kbd package contains keyboard control utilities as well as a big collection of fonts and keyboard layouts. Cyrillic setup with kkbbdd usually involves two things: 1. Screen font setup. This is performed by the setfont program. The fonts files are located in /usr/lib/kbd/consolefonts. NNOOTTEE:: Never run the setfont program under X because it will hang your system. This is because it works with low-level video card calls which X doesn't like. 2. Load the appropriate keyboard layout with the loadkeys program. NOTE: In RedHat 3.0.3, /usr/bin/loadkeys has too restrictive access permissions, namely 700 (rwx------). There are no reasons for that, since everyone may compile his own copy and execute it (the appropriate system calls are not root-only). Thus, just ask your sysadmin to set more reasonable permissions for it (for example, 755). The following is an excerpt from my cyrload script, which sets up the Cyrillic mode for Linux console: if [ notset.$DISPLAY != notset. ]; then echo "`basename $0`: cannot run under X" exit fi loadkeys /usr/lib/kbd/keytables/ru.map setfont /usr/lib/kbd/consolefonts/Cyr_a8x16 mapscrn /usr/lib/kbd/consoletrans/koi2alt echo -ne "\033(K" # the magic sequence echo "Use the right Ctrl key to switch the mode..." Let me explain it a bit. You load the appropriate keyboard mapping. Then you load a font corresponding to the _A_l_t codeset. Then, in order to be able to display text in _K_O_I_8_-_R correctly, you load a _s_c_r_e_e_n _t_r_a_n_s_l_a_t_i_o_n _t_a_b_l_e. What it does is a translation of _s_o_m_e characters from the upper half of the codeset to the _A_l_t encoding. The word 'some' is crucial here - not all characters get translated, therefore some of them, like IBM pseudographic characters get unmodified to the screen and display correctly, since they are compatible with the _A_l_t codeset, as opposed to _K_O_I_8_-_R. To ensure this, run mmcc and pretend you are back to MS-DOS 3.3... Finally, the magic sequence is important but I have no idea what on the Earth it does. I stole/borrowed/learned it from German HOWTO back in 1994, when it was like the only national language oriented HOWTO. _I_f _y_o_u _h_a_v_e _a_n_y _i_d_e_a _a_b_o_u_t _t_h_i_s _m_a_g_i_c _s_e_q_u_e_n_c_e_, _p_l_e_a_s_e _t_e_l_l _m_e. Finally, for those purists, who don't wont to give the _A_l_t codeset a chance, I'm attaching yet another version of the script above, using native _K_O_I_8_-_R fonts. if [ notset.$DISPLAY != notset. ]; then echo "`basename $0`: cannot run under X" exit fi loadkeys /usr/lib/kbd/keytables/ru.map setfont /usr/lib/kbd/consolefonts/koi-8x16 echo "Use the right Ctrl key to switch the mode..." However, don't expect nice borders in your text mode-based windowing applications. Now you probably want to test it. Do the appropriate bash or tcsh setup, rerun it, then press the right Control key and make sure you are getting the cyrillic characters right. The 'q' key must produce russian "short i" character, 'w' generates "ts", etc. If you've screwed something up, the very best thing to do is to reset to the original (that is, US) settings. Execute the following commands: loadkeys /usr/lib/kbd/keytables/defkeymap.map setfont /usr/lib/kbd/consolefonts/default8x16 NNOOTTEE:: unfortunately enough, the console driver is not able to preserve it's state (at least easily enough), while running the X Window System. Therefore, after you leave the X (or switch from it to a console), you have to reload the console russian font. 33..11..22.. FFrreeeeBBSSDD CCoonnssoollee I am not using FreeBSD so I couldn't test the following information. All data in this section should be treated as just pointers to begin with. The FreeBSD project homepage may have some information on the subject. Another good source is the relcom.fido.ru.unix newsgroup. Also, check the resources listed in section ``''. Anyway, this is what Ilya K. Orehov suggests to do in order to make FreeBSD console speak Russian: 1. In /etc/sysconfig add: keymap=ru.koi8-r keyrate=fast # NOTE: '^[' below is a single control character keychange="61 ^[[K" cursor=destructive scrnmap=koi8-r2cp866 font8x16=cp866b-8x16 font8x14=cp866-8x14 font8x8=cp866-8x8 2. In /etc/csh.login: setenv ENABLE_STARTUP_LOCALE setenv LANG ru_SU.KOI8-R setenv LESSCHARSET latin1 3. Make analogous changes in /etc/profile 33..22.. TThhee XX WWiinnddooww SSyysstteemm Like the console mode, the X environment also requires some setup. This involves setting up the input mode and the X fonts. Both are being discussed below. 33..22..11.. TThhee XX ffoonnttss.. First of all, you have to obtain the fonts having the Cyrillic glyphs at the appropriate positions. If you are using the most recent X (or XFree86) distribution, chances are, that you already have such fonts. In the late 1995, the X Window System incorporated a set of Cyrillic fonts, created by Cronyx. Ask your system administrator, or, if _y_o_u are the one, check your system, namely: 1. Run 'xlsfonts | grep koi8'. If there are fonts listed, your X server is already aware about the fonts. 2. Otherwise, run find -name crox\*.pcf\* to find the location of the Cyrillic fonts in the system. You'll have to enable those fonts to the X server, as I explain below. If you haven't found such fonts installed, you'll have to do it yourself. There is some ambiguity with the fonts. XFree86 docs claim that the russian fonts collection included in the distribution is developed by Cronyx. Nevertheless, you may find another set of Cronyx Cyrillic fonts on the net (eg. on ftp.kiae.su), known as the xxrruuss package (don't confuse it with the xrus program, which is used to setup a Cyrillic keyboard layout. Hopefully, tha letter one was renamed to xxrruusskkbb recently). XXrruuss has fewer fonts than the collection in Xfree86 (38 vs 68), but the latter one didn't go along with my ``Netscape'' setup - it gave me some really huge font in the menubar. The xxrruuss package doesn't have this problem. I would suggest you to download and try both of them. Pick up the one which you'll like more. Also, I'm going to creat RPM packages soon for both collections and download them to ftp.redhat.com. There are also older stuff, for example the vvaakkuuffoonnttss package, created by Serge Vakulenko, which was the base for the one in the X distribution. There are also a number of others. The important point is that the fonts' names in the old collection were not strictly conforming to the standard. The latter is fine in general, but sometimes it may cause various weird errors. For example, I had a bad experience with Maple V for Linux, which crashed mysteriously with the vvaakkuuffoonnttss package, but ran smoothly with the "standard" ones. So, let's start with the fonts: 1. Download the appropriate fonts collection. The package for XFree86 may be found at any FTP site, containing the X distribution, for example, directly from the XFree86 FTP site. The xxrruuss package may be found on ftp.kiae.su 2. Now when you have the fonts, you create some directory for them. It is generally a bad idea to put new fonts to the already existing font directory. So, place them, to, say, /usr/lib/X11/fonts/cyrillic for a system-wide setup, or just create a private directory for personal use. 3. If the new fonts are in BDF format (*.bdf files), you have to compile them. For each font do: bdftopcf -o .pcf .bdf If your server supports compressed fonts, do it, using the _c_o_m_p_r_e_s_s program: compress *.pcf Also, if you do want to put the new fonts to an already existing font directory. you have to concatenate the old and the new files named fonts.alias in the case both of them exist. 4. Each font directory in the X must contain a list of fonts in it. This list is stored in the file fonts.dir. You don't have to create this list manually. Instead, do: cd mkfontdir . 5. Now you have to make this font directory known to the X server. Here, you have a number of options: +o System-wide setup for XFree86. If you are running this version of X, then append the new directory to the list of directories in the file XF86Config. To find the location of this file, see output of startx. Also, see XXFF8866CCoonnffiigg((44//55)) for details. +o System-wide setup through xinit. Add the new directory to the xinit startup file. See xxiinniitt((11xx)) and the next option for details. +o Personal setup. You have a special start-up file for the X - ~/.xinitrc (or ~/.Xclients, or ~/.xsession for the RedHat users). Add the following commands to it: xset +fp xset fp rehash It is important to note that '+fp' means that the new fonts will be added to the head of the font path list. That is, if an application requests say a fixed font, it'll be given the one with Cyrillic char- acters, which is definitely what we are trying to achieve. There are problems, though. The fixed font in the cyrillic fonts dis- tribution doesn't have it's bold and italic counterparts. My font of choice is 6x13, so, since it also lacks bold and italic typefaces, I cannot use Emacs/XEmacs faces in their full glory. Hopefully somebody will ultimately create those fonts and the situation will change. 6. Now restart your X. If you have done everything right, the tests in the beginning of the section will be successful. Also, play with xxffoonnttsseell((11xx)) to make sure you are able to select the cyrillic fonts. In order to make the X clients use the Cyrillic fonts, you have to set up the appropriate X resources. For example, I make the russian font the default one in my ~/.Xdefaults: *font: 6x13 Since my cyrillic fonts are first in the font path (see output of This just a simple case. If you want to set the appropriate part of the X client to a cyrillic font, you have to figure out the name of the resource (eg. using eeddiittrreess((11xx))) and to specify it either in the resource database, or in the command line. Here go some examples: $ xterm -font '-cronyx-*-bold-*-*-*-19-*-*-*-*-*-*-*' ...will run xterm with some ugly font; and $ xfontsel -xrm '*quitButton.font: -*-times-*-*-*-*-13-*-*-*-*-*-koi8-*' ...will set a Cyrillic Times font for the QQuuiitt button in xfontsel. 33..22..22.. TThhee iinnppuutt ttrraannssllaattiioonn In the newest X releases (X11R61 and higher) there are two "standard" input methods: the original one, working through the xxmmooddmmaapp utility, and the new one called _X_k_b (X KeyBoard). The very first thing you have to do is ttoo ddiissaabbllee tthhee XXkkbb mmeetthhoodd!! Don't get charmed by it's ability to set up a "russian keyboard". It looks like this method is using the Cyrillic keysyms defined in keysymdef.h. This file defines keysyms for many languages. The only problem is that those definitions have nothing to do with the extended ASCII codeset - the one most programs are only able to operate with! I hardly know any programs being able to grok the keysymdef.h keysyms, different from 8-bit ASCII. However our goal is to get the KOI8-R support to work. To disable the Xkb support, browse through the Keyboard section of your XF86Config file and comment all lines starting with _X_k_b (case doesn't matter). Instead, put the following line: XkbDisable The xmodmap program.allows customization of codes emitted by various characters and their combinations. It sets the things up based on the file containing the translation table. In the previous versions of this document I used to describe the xmodmap-based setup in a great detail. This proved to be almost useless. The Xmodmap-based input translation method is well known as being it is non-portable, inflexible, and incomplete. Your configuration may work with one XFree version and fail with a different one. Even worse, sometimes things differ accross different servers in the same distribution. I strongly suggest you not to play with this xmodmap, at least for now. Apart from headache and disappointment you'll gain nothing. Instead, I recommend installing the xruskb package, which allows you to configure most of the input translation parameters without having to know about xmodmap. Again, the RedHat Linux users are free to download and install an RPM package. 33..33..

As an off-topic, if you want to make mmcc use color in an Xterm window, set the variable COLORTERM: COLORTERM= ; export COLORTERM 33..99.. rrllooggiinn Make sure that the shell on the destination site is properly set up. Then, if your rlogin doesn't work by default, use 'rlogin -8'. 33..1100.. zzsshh Use the same way as with csh (see section ``csh''). The startup files in this case are .zshrc or /etc/zshrc. 44.. EEddiittiinngg tteexxtt In this section I'll describe how to customize various text editors to work with Cyrillic text. This doesn't cover the _w_o_r_d _p_r_o_c_e_s_s_o_r_s, which will be described later (see section ``''). 44..11.. EEmmaaccss aanndd XXEEmmaaccss There are two version of the Emacs editor - GGNNUU EEmmaaccss and XXEEmmaaccss. While they provide more or less same functionality, some implementation details are significantly different. Cyrillic setup requires some low-level (in Emacs Lisp sense) tweaking, and it differs a bit for those two versions. NNOOTTEE:: Apart from the setup described here, there is an alternative way to configure both versions of emacs - use MMUULLEE (MULtilanguage Emacs support). The latter way is fairly complicated and (to the best of my knowledge) rarely used, so I don't discuss it here. The minimal cyrillic support in GGNNUU eemmaaccss (you don't have to do it for the XXEEmmaaccss) is done by adding the following calls to one's .emacs (provided that the Cyrillic character set support is installed for console or X respectively): (standard-display-european t) (set-input-mode (car (current-input-mode)) (nth 1 (current-input-mode)) 0) This allows the user to view and input documents in Russian. However, it isn't enough. Emacs doesn't know yet, that Cyrililic characters may constitute a word, let alon the upper/lower case conversion rules. In order to teach Emacs doing that, you have to modify the syntax and case tables of emacs: (require 'case-table) (let* ((ruc "\341\342\367\347\344\345\263\366\372\351\352\353\354\355\356\357\360\362\363\364\365\346\350\343\376\373\375\370\371\377\374\340\361") (rlc "\301\302\327\307\304\305\243\326\332\311\312\313\314\315\316\317\320\322\323\324\325\306\310\303\336\333\335\330\331\337\334\300\321") (i 0) (len (length ruc))) (while (< i len) (modify-syntax-entry (elt ruc i) "w ") (modify-syntax-entry (elt rlc i) "w ") (set-case-syntax-pair (elt ruc i) (elt rlc i) (standard-case-table)) (setq i (+ i 1)))) For this purpose I created a rusup.el file which does this, as well as a couple handy functions. You have to load it in your ~/.emacs. Finally, the russian.el package by Valery Alexeev (valery@math.uga.edu) allows the user to switch between cyrillic and regular input mode and to translate the contents of a buffer from one Cyrillic coding standard to another (which is especially useful while reading the texts imported from MS- DOS or Windows). 44..22.. UUssiinngg vvii The vvii editor (at least it's clone vviimm, available in most Linux distributions) is aware of 8-bit characters. It will allow you to enter cyrillic characters and will be able to recognize the word boundaries correctly. I don't know about the upper-/lower-case conversion rules, since I don't use vvii much. _I_f _y_o_u _k_n_o_w _s_o_m_e_t_h_i_n_g _a_b_o_u_t _i_t_, _p_l_e_a_s_e _i_n_f_o_r_m _m_e. 44..33.. EEddiittiinngg tteexxtt wwiitthh jjooee JJooee requires a special -asis option to recognize 8-bit characters. You may either specify this option at the command line, or to put it in ~/.joerc file (for personal use, or in /usr/lib/joerc for system-wide setup. If your program doesn't understand -asis option, you have to upgrade to the newer version. However, jjooee doesn't seem to understand the cyrillic words' boundaries correctly. I assume, that it applies both to the case conversion rules. 44..44.. SSppeellll--cchheecckkiinngg RRuussssiiaann The program I use to spell-check text is the GGNNUU iissppeellll. It is very flexible and extensible, so it is possible to use it to spell-check text in languages, other than English, by adding new _s_p_e_l_l _d_i_c_t_i_o_n_a_r_i_e_s. Constantine Knizhnik has created a very good Russian dictionary for iissppeellll. You may find it at his homepage. The distribution includes a handy incremental spelling script for eemmaaccss. Ideally, if you already have an iissppeellll properly installed, you have to just step into the newly-created directory and generate the dictionary, using the commands provided in the Makefile. However, chances are quite high, that you'll see a lot of complaints about the iissppeellll's unawareness of the 8-bit data. This is because in most distributions, iissppeellll is compiled without 8-bit data support. In this case, you cannot avoid recompiling the iissppeellll package. Again, RedHat users will be delighted to know that I've rebuilt the iissppeellll package with both Russian and German dictionaries. As usual, you may grab it from the RedHat FTP site. Once you have everything installed, you may invoke Russian spell- check, by supplying '-d russian' option to iissppeellll. Now, if you use EEmmaaccss, you may want to add a menu item for a russian dictionary. I sent a proposed menu entry to the ispell.el maintainer and he kindly agreed to include it in the the next public release of the file. Meanwhile, you may do it by adding the following code in your ~/.emacs (or in /usr/share/emacs/site-lisp/site-start.el for a system-wide setup): (setq ispell-dictionary-alist (append ispell-dictionary-alist '(("russian" "[\341\342\367\347\344\345\263\366\372\351\352\353\354\355\356\357\360\362\363\364\365\346\350\343\376\373\375\370\371\377\374\340\361\301\302\327\307\304\305\243\326\332\311\312\313\314\315\316\317\320\322\323\324\325\306\310\303\336\333\335\330\331\337\334\300\321]" "[^\341\342\367\347\344\345\263\366\372\351\352\353\354\355\356\357\360\362\363\364\365\346\350\343\376\373\375\370\371\377\374\340\361\301\302\327\307\304\305\243\326\332\311\312\313\314\315\316\317\320\322\323\324\325\306\310\303\336\333\335\330\331\337\334\300\321]" "[']" t ("-C" "-d" "russian") "~latin1")))) (define-key-after ispell-menu-map [ispell-select-russian] '("Select Russian (KOI-8)" . (lambda () (interactive) (ispell-change-dictionary "russian"))) 'british) Unfortunately, it won't work for the XXEEmmaaccss. I'll try to solve this problem later. 55.. UUssiinngg CCyyrriilllliicc wwiitthh mmaaiill aanndd nneewwss Setting up your mail and news software to recognize Cyrillic text is not very difficult, although you have to possess some knowledge of principles, mail and news work by. Internet electronic mail software generally consists of two parts: MMUUAA (Mail User Agent) and MMTTAA (Mail Transfer Agent). MUA is the program you use to read, compose, and send mail. However, MUA doesn't transfer mail messages by itself. Instead, it calls the MTA, which is reponsible to send message using an appropriate protocol to the appropriate direction. For example, your MUA may be PPiinnee and MTA - qqmmaaiill. Until quite recently, both MTA and MUA weren't 8-bit clean by default. Therefore, whenever you sent your message from say America to Russia, you were never sure, that some intermediate MTA won't strip the 8th bit from each character of your message. Therefore, a set of protocols was developed, which allowed encoding various kinds of data using only printable characters from 7-bit ASCII. This family of protocols is called MMIIMMEE (MultimedIa Mail Encoding). Since MIME is usually pre-configured to reasonable defaults, we won't describe it here. We will talk more about MIME when we provide a backward compatibility with other Cyrillic encodings (section ``''). Meanwhile, we start MUA setup, because it is usually up to an end- user. Then, we will describe the basic priciples of the MTA configuration for Cyrillic. 55..11.. SSeettttiinngg uupp MMaaiill UUsseerr AAggeennttss 55..11..11.. EEmmaaccss--bbaasseedd mmaaiill rreeaaddeerrss Basically, you don't need any special setup for Emacs-based readers, geivedn, that you've already configured the emacs itself (see section ``''). 55..11..22.. ppiinnee Set the following directive in ~/.pinerc for personal configuration, or in /usr/lib/pine.conf for a global one: character-set=ISO-8859-5 55..22.. CCoonnffiigguurriinngg yyoouurr MMTTAA There are a number of MTAs available now. These include sseennddmmaaiill, qqmmaaiill, ssmmaaiill, eexxiimm, and others. 55..22..11.. sseennddmmaaiill So far, sseennddmmaaiill is much more popular than other MTAs, because it's long history and widespread use. Personally, I hate this program - it is a perfect example of a completely moronic design and even it's "improvements" with the passion of time show, that this approach is not going to cease. Any system administrator shudders, when he hears the ominous "sendmail.cf" name... As of now, sseennddmmaaiill doesn't strip the 8th bit anymore. However, it may _e_n_c_o_d_e the 8-bit data using a special _b_a_s_e_6_4 encoding. Although most MUAs are supposed to recognize it and decode it back to a regular data, you may want to start with sending raw 8-bit text to make sure everything works. As of version 8, sseennddmmaaiill handles 8-bit data correctly by default. If it doesn't do it for you, check the EightBitMode option and option 7 given to mailers in your /etc/sendmail.cf. See _"_S_e_n_d_m_a_i_l_. _O_p_e_r_a_t_i_o_n _a_n_d _I_n_s_t_a_l_l_a_t_i_o_n _G_u_i_d_e_" for details. 55..22..22.. OOtthheerr MMTTAAss I don't know much about other MTAs. If you know something, which may be important for Cyrillic setup, please inform me. 66.. BBrroowwssiinngg tthhee CCyyrriilllliicc WWeebb Unlike e-mail and news, there is no definitive standard for Cyrillic encoding for the Web. This is primarily because Microsoft offers Web authoring tools, which only allow _c_p_1_2_5_1 codeset for Cyrillic, completely ignoring the fact that any other standards may already exist. The setup described here is very basic. It will allow you to view pages in the _K_O_I_8_-_R codeset. If the situation improves, I'll add more information. 66..11.. llyynnxx As of version 2.6, you may select the appropriate encoding for the display Character set option. 66..22..

NNOOTTEE:: This setup will work with most parts of the document. However, you won't be able to display Cyrillic text in the window header, menus and some controls. Attempts to fix it follows. 66..22..22.. CCyyrriilllliicc tteexxtt iinn ffrraammeess aanndd iinnppuutt aarreeaass To fix this, it is usually enough to: 1. Copy the Netscape properties database (usually Netscape.ad) to ~/Netscape. 2. In the latter file, set the following property: *documentFonts.charset*iso8859-1: koi8-r This will force all frame and input elements to use the fonts with _k_o_i_8_-_r encoding instead of the default ones, therefore you have to make sure you have installed such fonts (see section ``''). The bad news about the trick above is that if you load a document which is supposed to be displayed in iso-8859-1 fonts, it will be displayed using the koi8 fonts instead. Sometimes such documents will look worse. 66..22..33.. AAddvvaanncceedd sseettuupp Andrew A. Chernov is the one, who knows more than others about KOI-8 in general and netscape in particular. Visit his excellent KOI-8 page and download a patch for Netscape resource file, making Netscape speak Russian as much as it is able to. 77.. CCyyrriilllliicc wwoorrddpprroocceessssiinngg 77..11.. TTeeXX--bbaasseedd eennvviirroonnmmeennttss In this section I'll describe several ways to make TeX and LaTeX typeset Cyrillic texts. There are several ways, which differ in setup sophistication and usage convenience. For example, one possibility is to start without any preliminary setup and use the _W_a_s_h_i_n_g_t_o_n _A_M_S_T_e_X _C_y_r_i_l_l_i_c _f_o_n_t_s. On the other hand, you may install a LaTeX package, providing a very high degree of Cyrillic setup. I have an experience with two such packages. One is the cmcyralt package by Vadim V. Zhytnikov (vvzhy@phy.ncu.edu.tw) and Alexander Harin (harin@lourie.und.ac.za), and the other one is the LH package by the _C_y_r_T_U_G group with styles and hyphenation for LaTeX2e by Sergei O. Naoumov (serge@astro.unc.edu). I'll describe both. Note, that there are two versions of LaTeX available - 2.09 is the old one, while 2e is a new pre-3.0 release. If you are using LaTeX 2.09, then switch quickly to the 2e. The latter retains compatibility with the old one, but has much more features. Hopefully, version 3 will be released soon. I describe a LaTeX 2e setup. Also, both of these packages require the Cyrillic text to be typeset using the _A_l_t codeset, not _K_O_I_8_-_R! This is caused by historical reasons, since the creators of these packages used to work with EmTeX - the MS-DOG version of TeX (they didn't know about Linux yet :-). Switching to the _K_O_I_8_-_R requires some effort and is being expected to be done soon. So far, use some utility to convert your russian text from _K_O_I_8_-_R to _A_l_t. See section ``''. 77..11..11.. UUssiinngg tthhee WWaasshhiinnggttoonn CCyyrriilllliicc This package was created for the American Mathematic Society to provide documents with Russian references. Therefore, the authors were not very careful and the fonts look quite clumsy. This package is usually referred to as a "really bad cyrillic package for TeX". Nevertheless, we'll discuss it, because it is very easy to use and doesn't require any setup - this collection is supplied with most of TeX distributions. Of course, you won't be able to use such luxury as automatic hyphenation, but anyway... 1. Prepend your document with the following directives: \input cyracc.def \font\tencyr=wncyr10 \def\cyr{\tencyr\cyracc} 2. Now to type a cyrillic letter, you enter \cyr and use a corresponding latin letter or a TeX command. Thus, the lower case of the Russian alphabet is expressed by the following codes: a b v g d e \"e zh z i {\u i} k l m n o p r s t u f kh c ch sh shch {\cprime} y {\cdprime} \`e yu ya It is extremely inconvenient to convert your Russian texts to such encoding, but you can automate the process. The translit program (section ``'') supports a TeX output option. 77..11..22.. KKOOII--88 ppaacckkaaggee ffoorr tteeTTeeXX There is some new teTeX-rus package. It is reported to support KOI-8 character set and have all basic stuff required for TeX and LaTeX. I personally haven't tried it yes, although I heard about it's successfull usage.

UUssiinngg tthhee ccmmccyyrraalltt ppaacckkaaggee ffoorr LLaaTTeeXX The cmcyralt package can be found on any CTAN (Comprehensive TeX Archive Network) site like ftp.dante.de. You should obtain two pieces: the fonts collection from fonts/cmcyralt and the styles and hyphenation rules from macros/latex/contrib/others/cmcyralt. NNoottee:: Make sure you have the Sauter package installed, since cmcyralt requires some fonts from it. You can get this package from CTAN site as well. Now you should do the following: 1. Put the new fonts to the TeX fonts tree. On my system (Slackware 2.2) I created a cmcyralt directory in the /usr/lib/texmf/fonts/cm/. Create the src, tfm, and vf subdirectories in it. Put there .mf, .tfm, and vf files respectively. 2. Put the font driver files (*.fd) from the styles archive to the appropriate place (in my case it was /usr/lib/texmf/tex/latex/fd). 3. Put the style files (*.sty) to the appropriate LaTeX styles directory (in my case /usr/lib/texmf/tex/latex/sty). Now the hyphenation setup. This requires to remake the LaTeX base file. 1. The file hyphen.cfg contains the directives for both English and Russian hyphenation. Extract the one for Russian and place it to the LaTeX hyphenation config file lthyphen.ltx. In my case, that file was in /usr/lib/texmf/tex/latex/latex-base. 2. Put the rhyphen.tex to the same directory. It is needed for making the new base file. Later, you can remove it. 3. Do 'make' in that directory. Don't for get to make a link from Makefile to Makefile.unx. During the make process check the output. There should be a message: Loading hyphenation patterns for Russian. If everything goes OK, you will get the new latex.fmt in that direc- tory. Put it to the appropriate place, where the previous one was (like /usr/lib/texmf/ini/). DDoonn''tt ffoorrggeett ttoo ssaavvee tthhee pprreevviioouuss oonnee!!. This is it. The installation is complete. Try processing the examples found in the styles archive. If you are to create the PostScript files without any problems, then everything is OK. Now, to use Cyrillic in LaTeX, prepend your document with the following directive: \usepackage{cmcyralt} For more details, see the README file in the cmcyralt styles archive. NNoottee:: if you do have problems with the examples, provided you have installed the things right, then probably your TeX system hasn't been installed correctly. For example, during my first try, every attempt to create the .pk files for the russian fonts failed (MakeTeXPK stage). A substantial investigation discovered some implicit conflict between the _l_o_c_a_l_f_o_n_t and _l_j_f_o_u_r METAFONT configurations. It used to work before, but kept crashing after the cmcyralt installation. Contact your local TeX guru - TeX is very (sometimes too much) complicated to reconfigure it without any prior knowledge. 77..11..44..

Originally developed as a simple text-to-PostScript converter it became a big and highly configurable program with many options and allows you to manage various page layouts, syntax highlighting etc. Another tool (now available as a part of the _G_N_U project) is enscript. 88..11..11..

The author proved to be very open to suggestions, so since the release 4.9.8 aa22ppss supports Cyrillic right off-the-shelf. All you need is a PostScript printer. The command I use is: a2ps -X koi8r --print-anyway 88..11..22.. TThhee GGNNUU eennssccrriipptt The GNU eennssccrriipptt program is also designed for converting text to PostScript and it also has a non-ASCII codeset support. It doesn't have Cyrillic PostScript fonts, but it is very easy to get them, as will be explained below (thanks to Michael Van Canneyt): 1. Install the newest eennssccrriipptt. As of now, the most recent release is 1.5. You may either get the one from the GNU FTP archive, or take an RPM package from the Redhat site. 2. Now, if you are a lucky RedHat Linux user, download and install Cyrillic Textbook font . 3. If you don't use RPM, download a file textbook.tar.gz from the Cyrillic Software collection on sunsite.unc.edu . Extract it to a directory, where eennssccrriipptt fonts are located (usually /usr/share/enscript). Now change to that directory and run the following command: mkafmmap *.afm 4. The setup is finished. Try to print some text in KOI8-R Cyrillic with the following command: enscript --font=Textbook8 --encoding=koi8 some.file If you want a really quick and dirty solution and you don't care about the output quality and all you need is just Cyrillic on the paper, try the rtxt2ps package. It is a very simple no-frills text-to-PostScript conversion program. The output quality is not very good (or, to be honest, just _b_a_d) but it does it's job. 88..22.. TTeexxtt ttoo TTeeXX ccoonnvveerrssiioonn If all you need is just to print an ASCII text without any additional word processing, you may try to use some programs, which would convert your Cyrillic text to a ready-to-process TeX file. One of the best programs for such purposes is ttrraannsslliitt (see section ``''). In this case, you don't even have to bother about installing the Cyrillic fonts for TeX, since ttrraannsslliitt uses a _W_a_s_h_i_n_g_t_o_n _C_y_r_i_l_l_i_c package, which is included in most TeX distributions (or am I wrong?) 99.. CCyyrriilllliicc iinn PPoossttSSccrriipptt Experts say PostScript is easy. I cannot judge - I've got too many things to learn to spare some time to learn PostScript. So I'll try to use my sad experience with it. II''llll aapppprreecciiaattee aannyy ffeeeeddbbaacckk ffrroomm yyoouu gguuyyss wwhhoo kknnooww mmoorree oonn tthhee ssuubbjjeecctt tthhaann II ddoo (approx. 99% of the Earth population). Basically, in order to print a Cyrillic text using PostScript, you have to make sure about the following things: +o Cyrillic font is _l_o_a_d_e_d or included in the document. +o Cyrillic text is included in the document. +o Cyrillic text uses the appropriate character codes which correspond to the font's requirements. +o An appropriate font is _s_e_l_e_c_t_e_d in order to print Cyrillic text. There is no solution general enough to be recommended as an ultimate treatment. I'll try to outline various ways to cope with different problems related to the subject. One way to address Cyrillic setup problems generally enough is to use Ghostscript. GGhhoossttssccrriipptt (or just ggss in the newspeak) is a free (well quasi-free) PostScript interpreter. It has many advantages; among them: +o Ability to run on many platforms (various Unices, Windows etc) +o Support for a wide number of non-PostScript printers +o Good degree of configurability What is important in our particular case, is that once GGhhoossttssccrriipptt is set up, we can do all printing through it, thus eliminating extra setup for other PostScript devices (for example _H_P _L_a_s_e_r_J_e_t _I_V) 99..11.. AAddddiinngg CCyyrriilllliicc ffoonnttss ttoo GGhhoossttssccrriipptt This is important, since you probably don't want to put a responsibility to other programs to insert Cyrillic fonts in the PostScript output. Instead, you add them to ggss and just make the programs generate Cyrillic output compatible with the fonts. To add a new font (in pfa or pfb form) in ggss, you have to: 1. Put it in the ggss fonts directory (ie. /usr/lib/ghostscript/fonts). 2. Add the appropriate names and aliases for the font in the Fontmap file in the ggss directory. Recently a decent set of Cyrillic fonts for GGhhoossttSSccrriipptt appeared. It is located in ftp.kapella.gpi.ru. This one even has a necessary part to add to the Fontmap file. You have to download the contents of the /pub/cyrillic/psfonts directory. The README file describes the necessary details. 1100.. PPrriinntt sseettuupp Printing is always tricky. There are different printers from different vendors with different facilities. Even for a native printing there is no uniform solution (this applies not only to UNIX, but to other operating systems as well. Printers have different control languages and often they have very different views on foreign language support. The good news is that on control language seems to be recognized as a de-facto standard for print job description - it is a PostScript language developed by Adobe Corporation. Another problem is a variety of requirements to the print services. For example, sometimes you want just to print a piece if C program, containing comments in Russian, so you don't need any pretty-printing - just a raw ASCII output in a single font. Another time, when you design a postcard for your girlfriend, you'll probably need to typeset some document with different fonts etc. This will definitely require more effort to setup Cyrillic support. To accomplish the former task you just have to make your printer understand _o_n_e Cyrillic font and (maybe) install some filter program to generate data in appropriate format. To accomplish the latter one, you have to teach your printer different fonts and have a special software. There is also something in the middle, when you get a program which knows how to generate both the fonts and the appropriate printer input, so you can say do some aource code pretty-printing without sophisticated word processing systems. All these options will be more or less covered below. 1100..11.. PPrree--llooaaddiinngg CCyyrriilllliicc ffoonnttss iinnttoo aa nnoonn--PPoossttSSccrriipptt pprriinntteerr If you have a good old dot matrix printer and all you need is to print a raw KOI8-R text, try the following: 1. Find a proper KOI8-R font for your printer. Check out the MS-DOSish stuff on the Internet (for example the SimTel archive ). 2. Learn from the manual, how to load such font into your printer and, probably, write a simple program doing that. 3. Run this program from the appropriate rc file at a boot time. Thus, having Cyrillic characters in the upper part of the printer's character set will allow you to print you texts in Russian without any hussle. Alternatively to the _K_O_I_8_-_R fonts you may try to use the _A_l_t font. There are two reasons for that: +o It may be probably much easier to find an _A_l_t font, since those were very widespread in the MS-DOS culture. +o Having a proper _A_l_t font will allow you to print pseudo-graphic characters as well. However in this case, you'll have to convert your texts from _K_O_I_8_-_R to _A_l_t before sending them to a printer. This is quite easy, since there are a lot of programs doing that (see ``translit'' for example), so you just have to call such program properly in the if field in /etc/printcap file. For example, with the ttrraannsslliitt program you may specify: if=/usr/bin/translit -t koi8-alt.rus See pprriinnttccaapp((55)) for details. 1100..22.. PPrriinnttiinngg wwiitthh ddiiffffeerreenntt ffoonnttss One great way to cope with different printers and fonts is to use TTeeXX (see section ``''). TeX drivers handle all details, so once you make TeX understand Cyrillic fonts, you are done. Another possibility is to use _P_o_s_t_S_c_r_i_p_t. I decided to devote an entire chapter ``'' to the subject, since it is not simple. Finally, there are other word processors, which have printer drivers. I never tried anything apart from TeX, so I cannot suggest anything. 1111.. LLooccaalliizzaattiioonn aanndd IInntteerrnnaattiioonnaalliizzaattiioonn So far, I described how to make various programs understand Cyrillic text. Basically, each program required it's own method, very different from the others. Moreover, some programs had incomplete support of languages other than English. Not to mention their inability to interact using user's mother tongue instead of English. The problems outlined above are very pressing, since software is rarely developed for home market only. Therefore, rewriting substantial parts of software each time the new international market is approached is very ineffective; and making each program implement it's own proprietary solution for handling different languages is not a great idea in a long term either. Therefore, a need for standardization arises. And the standard shows up. Everything related to the problems above is divided by two basic concepts: _l_o_c_a_l_i_z_a_t_i_o_n and _i_n_t_e_r_n_a_t_i_o_n_a_l_i_z_a_t_i_o_n. By localization we mean making programs able to handle different language conventions for different countries. Let me give an example. The way date is printed in the United States is MM/DD/YY. In Russia however, the most popular format is DD.MM.YY. Another issues include time representation, printing numbers and currency representation format. Apart from it, one of the most important aspect of localization is defining the appropriate character classes, that is, defining which characters in the character set are language units (letters) and how they are ordered. On the other hand, localization doesn't deal with fonts. Internationalization (or _i_1_8_n for brevity) is supposed to solve the problems related to the ability of the program interact with the user in his native language. Both of the concepts above had to be implemented in a standard, giving programmers a consistent way of making the programs aware of national environments. Althogh the standard hasn't been finished yet, many parts actually have; so they can be used without much of a problem. I am going to outline the general scheme of making the programs use the features above in a standard way. Since this deserves a separate document, I'll just try to give a very basic description and pointers to more thorough sources. 1111..11.. LLooccaallee One of the main concept of the localization is a _l_o_c_a_l_e. By locale is meant a set of conventions specific to a certain language in a certain country. It is usually wrong to say that locale is just country- specific. For example, in Canada two locales can be defined - Canada/English language and Canada/French language. Moreover, Canada/English is not equivalent to UK/English or US/English, just as Canada/French is not equivalent to France/French or Switzerland/French. 1111..11..11.. HHooww ttoo uussee llooccaallee Each locale is a special database, defining at least the following rules: 1. character classification and conversion 2. monetary values representation 3. number representation (ie. the decimal character) 4. date/time formatting In RedHat 4.1, which I am using there are actually _t_w_o locale databases: one for the C library (libc) and one for the X libraries. In the ideal case there should be only one locale database for everything. To change your default locale, it is usually enough to set the LANG environment variable. For example, in sshh: LANG=ru_RU export LANG Sometimes, you may want to change only one aspect of the locale without affecting the others. For example, you may decide (God knows why) to stick with ru_RU locale, but print numbers according to the standard POSIX one. For such cases, there is a set of environment variables, which you can you to configure specific parts for the current locale. In the last exaple it would be: LANG=ru_RU LC_NUMERIC=POSIX export LANG LC_NUMERIC For the full description of those variables, see llooccaallee((77)). Now let's be more Linux-specific. Unfortunately, Linux libc version 5.3.12, supplied with RedHat 4.1, doesn't have a russian locale. In this case one must be downloaded from the Internet (I don't know the exact address, however). To check, locale for which languages you have, run 'locale -a'. It will list all locale databases, available to libc. Fortunately, Linux community is rapidly moving to the new GNU libc (glibc version 2, which is much more POSIX-compliant and has a proper russian locale. Next "stable" RedHat system will already use glibc. As for the X libraries, they have their own locale database. In the version I am using (XFree86 3.3), there already is a russian locale database. I am not sure about the previous versions. In any case, you may check it by looking into usr/lib/X11/locale/ (on most systems). In my case, there already are subdirectories named koi8-r and even iso8859-5. 1111..11..22.. LLooccaallee--aawwaarree pprrooggrraammmmiinngg With locale, program don't have to implement explicitly various character conversion and comparison rules, described above. Instead, they use special API which make use of the rules defined by locale. Also, it is not necessary for program to use the same locale for all rules - it is possible to handle different rules using different locales (although such technique should be strongly discouraged). From the sseettllooccaallee((33)) manual page: A program may be made portable to all locales by calling setlocale(LC_ALL, "" ) after program initialization, by using the values returned from a localeconv() call for locale - dependent information and by using strcoll() or strxfrm() to compare strings. SunSoft, for example, defines 5 levels of program localization: 1. _8_-_b_i_t _c_l_e_a_n software. That is, the program calls setlocale(), it doesn't make any assumptions about the 8th bit of each character, it users functions from ctype.h and limits from limits.h, and it takes care about signed/unsigned issues. It is very important _n_o_t to do any assumption about the character set nature and ordering. The following programming practices must be avoided: if (c >= 'A' && c <= 'Z') { ... Instead, macros from the ctype.h header file are locale-aware and should be used in all such occasions. 2. Formats, sorting methods, paper sizes. The program uses strcoll() and strxfrm() instead of strcmp() for strings, it uses time(), localtime(), and strftime()/ for time services, and finally, it uses localeconv() for a proper numbers and currency representation. 3. Visible text in message catalogs. The program must isolate all visible text in special _m_e_s_s_a_g_e _c_a_t_a_l_o_g_s. Those map strings in English to their translation to other languages. Selection of messages in an appropriate for a particular environment language is done in a way which is completely transparent for both the program and it's user. To make use of those facilities, the program must call gettext() (Sun/POSIX standard), or catgets() (X/Open standard). For more information on that see section ``''. 4. EUC/Unicode support. At this level, the program doesn't use the char type. Instead it uses wchar_t, which defines entities big enough to contain Unicode characters. ANSI C defines this data type and an appropriate API. For a more detaled explanation of locale, see, for example (``'') or (``''). 1111..22.. IInntteerrnnaattiioonnaalliizzaattiioonn While localization describes, how to adapt a program to a foreign environment, _i_n_t_e_r_n_a_t_i_o_n_a_l_i_z_a_t_i_o_n (or _i_1_8_n for brevity) details the ways to make program communicate with a non-English speaking user. Before, that was done by developing some abstraction of the messages to output from the program's code. Now, such mechanism is (more or less) standardized. And, of course, there are free implementations of it! The GNU project has finally adopted the way of making the internationalized applications. Ulrich Drepper (drepper@ipd.info.uni- karlsruhe.de) developed a package gettext. This package is available at all GNU sites like prep.ai.mit.edu. It allows you to develop programs in the way that you can easily make them support more languages. I don't intend to describe the programming techniques, especially because the gettext package is delivered with excellent manual. RReeqquueesstt ffoorr ccoollllaabboorraattiioonn:: If you want to learn the gettext package and to contribute to the GNU project simultaneously; or even if you just want to contribute, then you can do it! GNU goes international, so all the utilities are being made locale-aware. The problem is to translate the messages from English to Russian (and other languages if you'd like). Basically, what one has to do is to get the special .po file consisting of the English messages for a certain utility and to append each message with it's equivalent in Russian. Ultimately, this will make the system speak Russian if the user wants it to! For more details and further directions contact Ulrich Drepper (drepper@ipd.info.uni-karlsruhe.de). 1122.. SSttaayyiinngg ccoommppaattiibbllee Being standard is not the only issue. To be really nice, one has to provide the backward compatibility. In our case, this means that the configuration should be tolerant to the data created using non- standard character sets - that is the _A_l_t _(_c_p_8_6_6_) and _c_p_1_2_5_1 ones. Also, we should be able to run Cyrillic programs for MS-DOS. In most cases (except for HTTP), it is enough to provide a timely conversion of data to _K_O_I_8_-_R. When we talk about raw unstructured data, it is quite trivial - see section ``Conversion Utilities''. Another issue is the structured data. This case is more tricky. I'll try to outline the basic roadmap of fixing it. 1122..11.. MMIIMMEE--bbaasseedd ddaattaa ccoommppaattiibbiilliittyy _M_I_M_E is a standard for architecture-independent data representation. Originally developed for mail messages, it has now many more applications. MIME defines format, which is open to extensions and allows architecture-specific handling of data. For example, if I receive a mail message, containing a _M_I_M_E _o_b_j_e_c_t of the video/mpeg type (an encoded MPEG file), my mail reader will automatically decode it and start an MPEG player. Most UNIX programs, offering MIME capabilities, are based on the mmeettaammaaiill package, which contains a set of utilities and data files to work with MIME objects. Several configuration files (/etc/mailcap for global usage and ~/.mailcap for personal setup) define rules for handling MIME object of various types. Thus, if you receive a proper MIME data stream, containing text in one of the obsolete character sets, you may define a MIME rule to convert such text to KOI8. Below a number of MIME rules are shown, which are supposed to handle plain text and richtext objects, using both of the obsolete codesets, discussed above. You may incorporate these rules into one of the MIME configuration files. Note, that these rules use the ttrraannsslliitt package to perform the actual conversion. For more information on that program and the conversion in general see section ``Conversion Utilities''. text/plain; translit -t cp1251-koi8.rus < %s; test=test \ "`echo %{charset} | tr '[A-Z]' '[a-z]'`" = cp1251; copiousoutput text/richtext; translit -t cp1251-koi8.rus < %s; test=test \ "`echo %{charset} | tr '[A-Z]' '[a-z]'`" = cp1251; copiousoutput text/plain; translit -t alt-koi8.rus < %s; test=test \ "`echo %{charset} | tr '[A-Z]' '[a-z]'`" = cp866; copiousoutput text/richtext; translit -t alt-koi8.rus < %s; test=test \ "`echo %{charset} | tr '[A-Z]' '[a-z]'`" = cp866; copiousoutput text/plain; translit -t alt-koi8.rus < %s; test=test \ "`echo %{charset} | tr '[A-Z]' '[a-z]'`" = alt; copiousoutput text/richtext; translit -t alt-koi8.rus < %s; test=test \ "`echo %{charset} | tr '[A-Z]' '[a-z]'`" = alt; copiousoutput Obviously enough, this will work for plain text data only. Binary files are supposed to handle the codeset issues themselves (at least their "parent" applications are). Therefore, if you receive a Microsoft Word document in the _c_p_1_2_5_1 character set, the duty of providing appropriate conversion capabilities lays upon an application you use to read that document (for example Microsoft Word, or Applix Words). Unfortunately, the real situation is not that ideal. Many application have their own idea on how to use MIME. Until recently Microsoft Mail software had a broken MIME engine. Also, the Netscape Navigator/Communicator mail client is notorious because of it's sending of mail messages, encoded in _c_p_1_2_5_1 with the _c_h_a_r_s_e_t_=_k_o_i_8_-_r field in the message header and vice versa. 1122..22.. EExxpplliicciitt cchhaarraacctteerr sseett ccoonnvveerrssiioonn There are a lot of conversion routines for Cyrillic on the Internet. Each of them has it's own quirks and it's own degree of Cyrillic support. In my opinion tools must be standard. In this particular case the "standard" conversion tool is GGNNUU rreeccooddee. Unfortunately, the version, found on the official GNU site (3.4) doesn't support Cyrillic yet (only _I_S_O_-_8_8_5_9_-_5). I developed a set of conversion tables for _K_O_I_8_-_R, _A_l_t, and _c_p_1_2_5_1 for rreeccooddee and submitted them to the rreeccooddee maintainer. He promised to provide Cyrillic support in the upcoming release. Once it happens, I'll rewrite this section to recommend GGNNUU rreeccooddee as the standard conversion engine for Cyrillic. Meanwhile, I would recommend a translit package. It supports many popular codesets and is even able to produce a *TeX files (see section ``'') from text in Russian. Also, RedHat users will enjoy an RPM package for translit. For other conversion routines, Look at SovInformBureau or ftp.funet.fi. You can even use the special mode for emacs (see section ``Emacs''). 1122..33.. CCyyrriilllliicc iinn tthhee DDOOSS eemmuullaattoorr This seems to be the only application, which may require Alt Cyrillic character set. The reason is that Alt is native to DOS and most of DOS programs dealing with Cyrillic are Alt-oriented. For the console version (dos) you just have to load a keyboard and screen driver. Most of DOS drivers will work fine. I personally use the rrkk driver by A. Strakhov, which works for both console and X versions of ddoosseemmuu. Another choice is the r driver by V. Kurland (sorry for possible misspelling). It is perfectly customizable and supports many codesets, Alt and KOI8 among them. However it won't work for the X window (at least version 1.14 I'm using). Both drivers can be found on most Russian Internet sites, for example Kurchatov Institute FTP server . For the X version of ddoosseemmuu you have to provide an appropriate X font as well. Alex Bogdanov sent me such font by e-mail. It is an original vga font from the ddoosseemmuu distribution, modified for the Alt codeset. Unfortunately I don't know who is the creator of this font and where the official site is. To setup the font for dosemu you should +o Introduce this font to the X. This is described in ``X fonts setup''. +o Introduce this font to dosemu. If the font just replaces the original vga font, then it will be recognized by default. Otherwise, you have to describe it in /etc/dosemu.conf: # Font to use (without filename extensions). For example: X { updatefreq 8 title "MS DOS" icon_name "xdos" font "vga-alt"} Finally, you have to load a keyboard driver. Note, the you don't need a screen driver for the X window. Therefore, not all drivers will work. At least two will: rk by A. Strakhov, and cyrkeyb by Pete Kvitek. 1133.. BBiibblliiooggrraapphhyy 1. Andrey Chernov. KOI-8 . KOI-8 information and setup. 2.
