I'm not sure if A7 still supports this, but I believe it does. Back in the A5 days, fonts were based on bitmaps with all the letters arrayed in a grid. So if you made a font bitmap, but only used cyrillic letters, then you could work with that.

It'd be like a code, A = some cyrillic letter, B = another, etc.

Here is a link to a tutorial on making font bitmaps:
