Comment #1 From  Peter Hutterer (peter.hutterer@redhat.com)  2008-10-08 00:43:30 EDT   (-) [reply] -------

Victor, please file this bug upstream under the following URL:
https://bugs.freedesktop.org/enter_bug.cgi?product=xkeyboard-config

Sergey (the upstream maintainer) has a better overview on how to integrate new
keyboard layouts.

Once you have filed the bug, please add a reference to the bug in this
bugreport so we can track it and integrate it into Fedora when it is merged.

--------------

Description of problem:

There is an official Tajik Standard Keyboard Layout required by the
TojikStandard Organization to be used in software development. The official
keyboard layout, due to the added 6 special characters, does not support 4 important keys on the keyboard such as _-+= as they are replaced by special characters “ғ” and “ӯ” on Tajik keyboard.
The official Tajik Standard Keyboard Layout already exist in Windows Vista (under wrongly spelled “ta” locale)

For the translators in Linux (in Mandriva distribution) a Tajik keyboard was developed to match the Russian layout and have all the Tajik 6 special keys also available on the keyboard. This unofficial Tajik keyboard layout use more than one buttons to get a letter with a special sign for Tajik language and require two key strokes. The existing Tajik xkb in Fedora is based on unofficial layout.

To meet the requirements and translators needs for both official and unofficial layouts, the following
layout has been created to resolve the existing.

Tajik users/typers would like to have an option in Fedora to use/have both kayboard layouts:

1) Standard Tojiki Keyboard Layout, Official Standard, Required
2)  Tojiki Rusi Keyboard Layout, Unofficial, But most usable

Both methods provided below:
