I've discovered that there are (at least) three Bulgarian keyboard layouts that are (or have been) commonly used in Bulgaria.
1. The Bulgarian typewriter layout: http://en.wikipedia.org/wiki/File:Bulga … layout.svg
2. The traditional phonetic layout: http://en.wikipedia.org/wiki/File:Keybo … onetic.png
3. The newer phonetic layout: http://commons.wikimedia.org/wiki/File: … netic2.png
Can anyone tell me which of these three keyboards would be most familiar to mobile phone users in Bulgaria? That is, if I were designing a keyboard for a touchscreen phone, which of these keyboard layouts would I use?
Thanks,
RP
