[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.
