The Linux Thai HOWTO Poonlap Veeratanabutr, poon-v@fedu.uec.ac.jp v0.2, 26 May 1997 This document describes how to set Linux to use Thai language. This means at least, you can read and write Thai plain text document, name filename in Thai and use some applications with Thai characters. I use Linux Slackware96, the path name I describe here may different to other distributions. 1. Introduction My motivation comes from ZzzThai Project by uecthai@fedu.uec.ac.jp , which describe how to use Thai with many computer platforms. I joined this project, started from windows95 then I felt Linux is more interesting. This is the first version of Thai HOWTO. It is not complete yet. The things I did not describe here, printing Thai document, Thai Tex, console fonts, etc. I will try to describe these in later version. Thai standard character codes is TIS620. Thai character codes are in the same range as iso_8859_1, so we can treat it as iso_8859_1 type. It is tricky. With X11R6 there is information about Thai in /usr/X11/include/X11/keysymdef.h and /usr/X11/lib/X11/locale/th_TH.TACTIS. You may look in these directory or file for your information. I tried to use those information but it did not work. For now, it is better to treat Thai character as iso_8859_1 and it works well. Thai characters are not like Latin characters. There are many position in Thai character, normal position, character on other characters, character under other characters. There is not space in sentences. These are some problems in developing Thai word-processor. 2. Thai Input and Output 2.1. Linux console 2.1.1. Thai fonts You can obtain Linux Thai console fonts which created by Phaisarn Techajaruwong from ftp://ftp.fedu.uec.ac.jp/pub/thai/UEC/ZzzThai/Software/Linux/Fonts You can load the new font from Linux console by command %setfont ThaiFont You should put Thai fonts(psf format) in /usr/lib/kbd/consolefonts/. If you want Thai font to be loaded automatically when you boot the machine, create the file /etc/rc.d/rc.font as the following. #!/bin/sh # # This selects your default screen font from among the ones in # /usr/lib/kbd/consolefonts. # setfont phaisarn.psf 2.1.2. Keyboard layout You can set keyboard behavior as you like by using loadkeys command. Usually, you use loadkeys to load the file located in /usr/lib/kbd/keytables. You can create mapping file and save in this directory. This is the sample. # thai.map # This thai.map was modified by Poonlap Veeratanabutr (poon-v@fedu.uec.ac.jp) # from us.map.

To load this file %loadkeys thai.map To switch to Thai input press the right Alt key. If you want to switch to English press the right Alt key again. To set Thai keymap as default, after you put thai.map in /usr/lib/kbd/keytables create the file /etc/rc.d/rc.keymap like the sample. #!/bin/sh # # Loadkeys will look for thai.map in /usr/lib/kbd/keytables # loadkeys thai The thai.map will be automatically loaded when you boot the machine. 2.2. X Window system 2.2.1. Thai fonts To display Thai characters in X Window system, you must have Thai fonts for X Window system. You can obtain Thai fonts in bdf format or pcf format on internet. ftp://ftp.fedu.uec.ac.jp/pub/thai/UEC/ZzzThai/Software/UNIX/Fonts ftp://thaigate.rd.nacsis.ac.jp/pub/thaisoft/titech-aima http://www.nectec.ac.th/pub/software/i18n/thai These fonts usually come in tar or gz format. You must extract it by using command tar or gunzip. You will get a lot of 2.2.1.1. Installing Thai fonts You must log in as root. Let's put Thai fonts in /usr/X11/lib/X11/fonts/misc/ change directory to /usr/X11/lib/X11/fonts/misc/ and run command #mkfontdir This command will update font database file. If you run this command in X Windows system, you may need to restart X window to take effect. 2.2.2. Thai keyboard layout You can use the utility xmodmap to map your keyboard as you want. Normally xmodmap is used to load the the file. There is the file .Xmodmap in /use/X11/lib/X11/xinit/. This file will be load if you don't have ~.xinitrc/ and .Xmodmap(in Slackware 96). The file /usr/X11/lib/X11/xinit/.Xmodmap doesn't map all keys. It only solves the Backspace/Delete key's problem. The following is the sample .Xmodmap for Thai Kedmanee keyboard layout. ! !

Put this layout personally, put this sample file in your home directory. If you have .xinitrc or .xsession in your home directory, add the following line in those files. xmodmap ~/.Xmodmap Thai/US toggle key is assigned to keycode 0x4E (78), Scroll Lock key with the statement keycode 0x4E = Mode_switch XF86ModeLock XF86ModeLock is the special keysym for XFree86 X server. If you don't add this keysym, you have to hold the scroll lock key while you are typing Thai characters. 3. Applications with Thai characters This is the tricky part. Most applications support iso_8859_1 characters or 8-bit characters. For example, emacs can display iso_8859_1 character. If we set emacs to display iso_8859_1 and use Thai font, you can edit Thai document with emacs. You should define the environment LC_CTYPE to iso_8859_1 in /etc/profile (for bash users) and /etc/csh.cshrc (for tcsh users). Similarly you should (for the sake of principle) put something like this in your *basicLocale: C *timeFormat: C *numeric: C *displayLang: iso_8859_1 *inputLang: iso_8859_1 If you use libc-4.x.xx you should set LC_CTYPE to ISO-8859-1 instead of iso_8859_1. These are some of applications which can use with Thai characters and how to config them. To make X window application displays Thai font, you should run the application with -fn option. For example, #xterm -fn NameOfThaifont If you don't want to fill -fn option every time you run application. You should set Thai font in your ~/.Xdefaults or ~/.Xresources like this XTerm*font: NameOfThaifont 3.1. Non-network applications 3.1.1. xterm There are several programs running under xterm such as shell, pine, vi, etc. Don't forget to use Thai font with xterm as I mention above. bash : New versions of bash (v1.14.1+) only need to have LC_CTYPE set to iso_8859_1, but if you have problems put the following in your /etc/inputrc or ~/.inputrc file: set meta-flag on set convert-meta off set output-meta on I reccomend you to use ~/.inputrc because Thai character set is 8-bit but not exactly iso-8859-1. You should avoid to set LC_CTYPE as ISO_8859_1 if you can. You can type Thai characters in command line. That means you can name filenames in Thai. tcsh : Put the following in your /etc/csh.cshrc or .tcshrc file: setenv LC_CTYPE iso_8859_1 Note: If this doesn't work, your copy of tcsh was probably not com­ piled with NLS support or possibly it's version 6.03 or lower. ls : Issue the command as ls -N or possibly ls --8bit You may set alias in ~/.bashrc or ~/.cshrc, so you can type ls without option. If you don't use ls with -N option, you may see Thai filename as ?????. less : Set the following environment variable: LESSCHARSET=latin1 3.1.2. emacs In version 19.26 or later of GNU emacs for X11 you can simply set the environment variable LC_CTYPE to iso_8859_1. If you use an older version or use emacs under plain Linux put the following in your ~/.emacs or the the system-wide initialization file (probably /usr/lib/emacs/site-lisp/default.el): (standard-display-european t) (set-input-mode (car (current-input-mode)) (nth 1 (current-input-mode)) 0) If you run emacs already, press Esc-x and type standard-display- european in minibuffer, this command will tell emacs to display 8-bit character. If you use bash shell you can run emacs in this way, %LC_CTYPE=iso_8859_1 emacs This will set LC_CTYPE=iso_8859_1 for emacs only. Because some Thai characters have 0 width, cursor's position may be not in the right place. you should use the fonts from mule. You can get these fonts from ftp://ftp.fedu.uec.ac.jp/pub/thai/UEC/ZzzThai/Software/UNIX/Fonts/Mule/etl_fonts.tar 3.1.3. vi Vi should be run on xterm that uses Thai font. 3.1.4. xedit Run xedit with -fn option like xterm. This application can display Thai characters in the right position. 3.2. Network applications 3.2.1. E-mail You can not send Thai E-mail with mail command. Mail command transfers mail in 7 bit. You should use mail application that supports MIME such as pine or elm. elm: Put the following definitions in your ~/.elm/elmrc file: charset = iso-8859-1 displaycharset = iso-8859-1 textencoding = 8bit This may not work on some versions of elm. pine : Put the following definition in your ~/.pinerc file: # Reflects capabilities of the display you have. Default: US-ASCII. # Typical alternatives include ISO-8859-x, (x is a number between 1 and 9). character-set=ISO-8859-1 This can also be set via the Setup option in pine. You can find it under Config. 3.2.2. tin Put the following definitions in your ~/.tin/headers file: Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit Now you can post messages with the proper Danish characters in the message body. 3.2.3. lynx Put the following definition in your ~/.lynxrc file: character_set=ISO Latin 1 This can also be set via the Options menu in lynx. Type `o' and set the relevant option. 3.2.4. telnet Put one line of the following type in your ~/.telnetrc file for each host you want to log on to using telnet: set outbinary true Example: localhost set outbinary true foo.bar.dk set outbinary true 3.2.5. Netscape If you have Thai fonts in your system. You just select Thai fonts from Options | General Preferences | Fonts. Thai fonts will appear in ISO-8859-1 or in User defined. 4.
