experimental mini-HOWTO for Linux (Unix) to setup international
   keyboards.
   
   This xmodmap and kimap solutions will work for you in setting up any
   international keyboard for (Debian, RedHat, Mandrake, Corel Linux)
   Linux, FreeBSD, OpenBSD, NetBSD and possibly every Unix that uses
   Xfree86 and KDE. The advantage of this package is that it is not
   architecture specific and will work on SPARK, MIPS and all other
   systems. I don't want to say that other packages are architecture
   independent, but I don't like writing garbage in the bash_profile and
   XF86Config or possibly somewhere else. This was written by Juraj Sipos

   INTRODUCTION
   
   Imagine you use Linux or a BSD OS and want to write a business letter
   to a person that has a foreign name with a slash or idiaresis. Danish
   language uses signs like ø and Portuguese like ñ. With this
   information you can make your own international keyboard layout
   without installing any additional packages. The following information
   will help you set up German, Spanish, Italian, Slovak, Czech, Polish,
   Slovenian, Croatian, Danish, Dutch, French, Finnish, Norwegian,
   Estonian, Latvian, Swedish and other keyboards without additional
   installing of national packages and without writing garbage to
   bash_profile and XF86Config files. You can also alternatively look at
   my homage at [2]http://www.home.sk/www/man/bsd1.htm
   to see pictures of various keyboards. In case you want to install
   Greek, Hebrew or Russian language, follow my information and apply
   changes pertinent to these languages (e.g., to install Greek fonts,
   etc.).
   
   The biggest problem with kikbd or international keyboard under KDE in
   X Windows is that it doesn't work in Xfree86 that easily (you have to
   install some national packages and write garbage with complicated
   syntax to the above-mentioned files). A user expects a simple way for
   configuring his or her keyboard for international settings. A simple
   way is to start KDE, change the international keyboard settings and
   immediately write in the language we chose (this will work for German
   and other languages, but in Eastern European keyboards some letters
   don't function). According to the KDE documentation it should work,
   but it doesn't. After exploring many KDE resources on the net, I
   didn't find a solution (except for the one that forces you to install
   some national package). I know that some locale settings should be
   included in my bash_profile or csh logic scripts, but after applying
   these settings I couldn't change (and install) keyboards in FreeBSD
   and it appeared like going through a darker forest compared to the
   information I already had regarding localization of KDE and X Windows
   under Xfree86.
   
   Here are some solutions for installing international keyboard
   layouts.  The following information will help you set up any European
   keyboard layout. The solution works for Xfree86 in 3.1 RELEASE in
   FreeBSD (.Xmodmap solution), Corel Linux, Debian Linux, RedHat and
   FreeBSD 3.3 RELEASE and 4.0 RELEASE (KDE *.kimap solution). I tested
   it on those systems. Note: .Xmodmap solution works well with other
   windows managers. Some Unixes override .Xmodmap setting when used with
   KDE. If .Xmodmap doesn't work, change must be made to the KDE kimap
   files in .../kikbd directory.
   
   If .Xmodmap solution doesn't work in KDE, copy skz.kimap (at the end
   of this article) to /usr/local/share/apps/kikbd, which is your KDE
   keyboard directory. The problem with KDE is that after installing
   another keyboard, you have no chance to use it as KDE documentation
   doesn't clearly state how to define your locale settings in a
   bash_profile. After I installed Slovak keyboard in KDE, I couldn't
   write in Slovak or Czech, so I made few changes to skz.kimap file,
   which are explained later in this file. After applying these changes,
   no other changes are necessary - you don't need to write any special
   commands to your bash_profile or XF86Config. BUT WHEN YOU INSTALL
   ANOTHER KEYBOARD in START/SETTINGS/INPUT DEVICES/INTERNATIONAL
   KEYBOARDS from your KDE menu, CHECK AUTOSTART. Then everything will
   work fine.  The difference between skz.kimap and sky.kimap (and
   csz.kimap and csy.kimap) is that y,Y and z,Z are swapped, so with
   skz.kimap or csz.kimap you will have z,Z instead of y,Y, but with
   sky.kimap or csy.kimap, y,Y doesn't change its position on the IBM
   English keyboard layout.
   
   How it all works:
   
   a) Copy the "Compose" file from /usr/X11R6/lib/X11/locale/iso8859-2
   to:
      /usr/X11R6/lib/X11/locale/iso8859-1  directory (yes, iso8859-1, not
   iso8859-2). Back up
      the original "Compose" file if you want (alternatively, copy other
   iso885*** Compose
      file to iso8859-1 directory).
   b) Put the included .Xmodmap file to your root directory (Slovak
   language, or make your own
      .Xmodmap file) (or possibly put your own *.kimap file to the kikbd
   directory if Xmodmap
      will not work)
   c) Install ISO8859-2 fonts (or other pertinent fonts).
   d) Disable every "Scroll lock" uncommented line in your XF86Config,
   because our .Xmodmap
      uses scroll lock to switch between keyboards.
   e) Put the appropriate fontpath for your newly installed fonts in your
   XF86Config file, if
      necessary.
   
   The .Xmodmap solution may be applied to all  X keyboards except
   Hebrew, I suppose (I'm joking). The .Xmodmap file overrides all
   settings of keyboard layouts as defined in
   /usr/X11R6/lib/X11/xkb/symbols/, where are symbols for many
   international keyboards. The .Xmodmap solution will give you an
   enhanced Slovak typewriter keyboard layout.
   
   First, I must say that in my solution, different mapping is used for
   .Xmodmap file (and kimap file) for some ISO definitions. This means
   that the ISO definitions will either give you what they say they are
   (aacute [á], eacute [é], etc.), or they will not give you what they
   say they are (putting "threequarters" in your .Xmodmap file will give
   not give you "3/4" but "z" with a caron above it). For example, "mu"
   will give lcaron, "oslash" rcaron, etc. (Obviously, in other case you
   need to install some national packages to use "lcaron" definition
   instead of "mu"). Normally, you can not put "lcaron" to the .Xmodmap
   file, because it will not give you lcaron; you must write "mu"
   instead, or "guillemotright" for tcaron. I also tried hexadecimal
   numbers and they work. However, other  key definitions, for example,
   adieresis (a with two dots above it), uacute (u with slash above it),
   as well as dead_diaeresis do not require a substitution of other
   definitions and work pretty well as they're defined everywhere (dead
   key is a key  you press, you hold it and nothing happens, but after
   pressing another key you will get a special letter). The original
   "Compose" file in .../iso8859-1 directory can be fully utilized for
   Slovak or Czech keyboard layouts (Polish, Hungarian, Slovenian,
   Croatian), but there is only one problem with the Slovak or Czech
   keyboard (and other languages too) layout - dead_caron doesn't work.
   That's why you have to copy the "Compose" file from the iso8859-2
   directory to iso8859-1 directory, or alternatively, you can edit the
   "Compose" file in iso8859-1 directory and put all references about
   "dead_caron" from iso8859-2/Compose to iso8859-1/Compose file.
   
   You can leave the Keyboard section in your XF86Config without much
   change. Put (if it's not already there) the following in the
   "Keyboard" section:
   
   Section "Keyboard"
   Protocol "Standard"
   XkbRules "xfree86"
   XkbModel "pc101"
   XkbLayout "us"
   
   Some X Windows managers and/or environments override .Xmodmap
   settings, so if you use KDE and .Xmodmap doesn't work, use kikbd
   keymap instead of .Xmodmap. (A sample kikbd kimap for the Slovak
   language is included at the bottom of this file). The
   Slovak/Czech/English keyboard layout  is switched to by scroll lock
   with .Xmodmap. You may use languages only with the applications that
   have access to your ISO-8859-2 (or other fonts) fonts (this may not
   work with StarOffice or with other applications that have their own
   built-in fonts). StarOffice has its own fonts directory - afm fonts in
   ../xp3/fontmetrics/afm, and ps fonts in ../xp3/pssoftfonts, so you
   must add the ISO8859-2 fonts directory to these directories (to tell
   StarOffice to use these fonts too) and edit fonts.dir file and add the
   symlinked fonts there. I can easily use any language in StarOffice.
   
   Important note: If you want to exchange documents between StarOffice
   or WordPerfect and MS Word, you must include the information about
   windows 1250 encoding to the file you write (win1250 is similar to
   iso8859-2, but it's a little bit different). There's a solution: use a
   converter from iso8859-2 to win1250 (you can find one at my home page
   at [3]http://www.home.sk/www/man/bsd1.htm).
   
   If you want to edit and make your own .Xmodmap keyboard layout
   definitions, I'll explain one line of the .Xmodmap file to make clear
   what you should do. This explanation can be used for all keycodes.
   
   For example, the line:
   
   keycode 0x11 = 8 asterisk aacute 8
   
   (note: keycode 0x11 is derived from xkeycaps utility)
   says that the first pair, the default one, (number "8" and "asterisk")
   will display number "8" when you press keycode 0x11 ("8"), will
   display asterisk when a "shift" key is pressed. After pressing the
   scroll lock, there's another definition: ISO_NEXT_GROUP, which means
   that when you press the default "8" key, no "8" will be displayed, but
   aacute ("á"), when you press the "shift" key, number "8" will be
   displayed. So if you change "aacute" and "8", anything you put instead
   of "aacute" and "8" will be displayed, for example:
   
   keycode 0x11 = 8 asterisk semicolon colon
   
   will give you "semicolon" and "colon" in your 0x11 keycode after
   pressing the scroll lock. If you delete the ISO_NEXT_GROUP (the next
   pair of definitions on the right), you will have only one group of
   keyboard definitions ("8" and "asterisk"). Be careful when editing the
   .Xmodmap file. You mustn't delete definitions that enable utilization
   of the scroll lock unless you know what you are doing. These are the
   lines such as:
   
   keycode 0x4e = ISO_Next_Group
   add mod5 = ISO_Next_Group
   
   etc. You must also keep in mind that Unixes are case sensitive.
   
   If you want to find out more about keycodes, install a package
   "xkeycaps".

   The purpose of the following info is to help you build any .Xmodmap
   keyboard layout with iso8859-2 or other character sets.  If you're
   going to use other languages than the Central European ones, find a
   pertinent table for your ISO*** character set on Internet. The
   gdkkeysyms.h file is in (RedHat) /usr/include/gdk/gdkkeysyms.h and it
   contains all the special names we're using here (it also contains
   names of Greek characters).
   
   UNIX
   
   ISO-8859-2 (ISO Latin2) character set
   
   octal hex (you can use it for other languages too)
   
   ----------------------------------------------------------------------
   First, try to see if definitions will give you (after installing
   pertinent fonts and keyboard in X) what they say they are. If they
   will not give you what they say they are (some keycodes will be
   unfunctional), then you must make a substitution. Definitions which
   will not give you what they say they are can be traced by their visual
   shape in Western Latin 1 encoding. For example, if you load a Slovak
   website, do not use ISO8859-2 character set encoding for viewing, but
   Western ISO8859-1 encoding for viewing. Thus you will see bad fonts
   with letters like ¾ and so on. You will see what you must substitute.
   But if you don't know what "¾" is called in ISO terminology, find and
   download an appropriate character set table for ISO-8859-1. It must be
   somewhere on the net. The symbols on your right (for example, mu
   [micro], which is µ, will give you lcaron instead of µ) will give you
   what's on their left. NOTE: vowel *acute signs require no
   substitution, therefore I omitted iacute (í), aacute (á), etc.
   
   0243 0xa3 /Lslash £     (Explanation: writing the name of £ ["pound"
   in our case]
                           to Xmodmap or kimap file will give you Lslash.
   But Lslash can be
                           obtained by a dead_caron - you press a
   dead_caron and L). The sign
                           on the right, if put in Xmodmap or kimap
   files, will
                           print you the character which is on its left
   0245 0xa5 /Lcaron ¥     Thus, writing "yen" to kimap or Xmodmap file
   will give us Lcaron
   0251 0xa9 /Scaron ©     copyright (will give us Scaron)
   0253 0xab /Tcaron «     guillemotleft (will give us Tcaron)

   0376 0xfe /tcedilla þ
   0377 0xff /dotaccent ÿ
   
   You may experiment to find out which definitions will give you which
   characters, it shouldn't be difficult. This is just a hint on how to
   start. I didn't go on to investigate further definitions because I
   have my Slovak and Czech keyboards and I'm not, for now, interested to
   use other keyboards.  Look at my homage and build your own keyboard.
   
   Enjoy.
