Wow, thank you for this response. This is actually fascinating and frustrating at the same time. So Bulgarian uses the same Unicode points, but also uses the language/culture metadata to let the font know which set to use.

I'm building out a multi-lingual wiki and just about to start adding Cyrillic support, and this really helps me understand that there is more research I need to do to support other Cyrillic languages.
