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:

Recently I wanted to add Chuvash localization to the jQuery UI datepicker. Unfortunately, my pull request was rejected. The reason is that jQuery UI will be using Globalize framework: The jQuery Globalize framework relies on CLDR, so What is Unicode CLDR (Common Locale Data Repository)?

The Unicode CLDR provides key building blocks for software to support the world’s languages, with the largest and most extensive standard repository of locale data available. This data is used by a wide spectrum of companies for their software internationalization and localization, adapting software to the conventions of different languages for such common software tasks

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]
