The Chuvash keyboard layout has been the Russian keyboard layout with 4 Chuvash letters that are typed by pressing the right Alt button plus the base letter. Some of the arguments have been

1. Users don’t need to switch or learn a new keyboard layout. They can keep on typing Russian texts and sometimes Chuvash texts
2. It is easy to communicate about how the right Alt button works. The Right-Alt-technique is also used in Esperanto, Polish and other languages.
3. The letters are placed according the labels

Recently two major events happened that made the question about the Chuvash keyboard layout important:

In my spare time I am currently working on a Chuvash-Tatar phrasebook. I have used the Chuvash and Tatar keyboard layout on Linux. They work fine, but switching between them takes time. So I decided to add Tatar letters (right Alt + combinations) to my Chuvash keyboard layout. While adding it I found a combined Russian-Ukranian United keyboard layout and I thought:

• What if I create a new keyboard layout for Russian that will have almost all additional Cyrillic letters? A Russian Extended keyboard layout could be based on the Russian keyboard layout and have other non-Russian letters.

This is what I have come up to so far. The definition can be found on my project at github: russian-extended-kbd. I will update it more and provide more info about how it is organized and how to install it. I’ll also try to implement it for Windows and maybe for Mac (I doubt it, everything is so locked-down there). This is just a proof-of-concept so far. It only works on Linux (with xkb). Nevertheless, some key characteristics of this layout:

[caption id=“attachment_3165” align=“alignnone” width=“630”] Proto-Bulgarian Runes (Chuvash language is the closest language to the Proto-Bulgar language). Wonder if they are supported in Unicode :)[/caption] The Chuvash Computer Keyboard layouts have existed since 2001, but due to the lack for Unicode support we were forced to use the look-alike letters  from other latin-based keyboard layouts. On Linux The Chuvash keyboard layout was added in [2007](https://bugs.freedesktop.org/show_bug.cgi?id=11246 “The original “bug” in FreeDesktop bugzilla”) and Linux is still the only operating system that has a native keyboard layout for Chuvash language. On Windows we have used the Keyboard Layout Creator and distributed it as an executable file. Today, when Windows XP is not supported anymore, the majority of users now have full support for the correct Chuvash letters from the Extended Cyrillic table. These four Chuvash letters are “additional” to the Russian alphabet: Ӑ, Ӗ, Ҫ and Ӳ. Now when new “keyboards” appear on Android, in web browser (they use the standardized letters) and hopefully in Windows and iOS, we have to consider put the correct letters into the keyboard layouts. For Linux the /usr/share/X11/xkb/symbols/ru file has to be updated: [code] // Chuvash language layout // Anatoly Mironov @mirontoli partial alphanumeric_keys xkb_symbols “cv” { include “ru(winkeys)” name[Group1]= “Chuvash”; key.type[group1]=“FOUR_LEVEL”; key { [ Cyrillic_u, Cyrillic_U, 0x010004f3, 0x010004f2 ] }; key { [ Cyrillic_ie, Cyrillic_IE, 0x010004d7, 0x010004d6 ] }; key { [ Cyrillic_a, Cyrillic_A, 0x010004d1, 0x010004d0 ] }; key { [ Cyrillic_es, Cyrillic_ES, 0x010004ab, 0x010004aa ] }; include “level3(ralt_switch)” }; [/code]

I can’t write in Chuvash in Windows 8 (and all the previous Windows releases). Chuvash is a minority language in Russian Federation. In this blog post I want to summarize the status of the keyboard layout support of the minority languages of Russia and find a way to improve this situation.

Languages and Microsoft

There are thousands of languages. Of course it is hard to support them all. As per 2012-02-21 Windows 8 supports 109 (!) languages. In december 2012 the support for Cheerokee language was added.
