Non-english texts support (?)

[tsss]

Hi!
I like to make a non-english ToME game. I try unicode string in some ToME data, and used some display drivers, but failed. Get 6 simbbols instead of 3 and different kind.
Lua docs about unicode says that lua corretly store utf8 strings, so the problem probably in a way tome handle output.
It's probably well known issue about not supporting unicode, but forum search don't give answers. So, please help.

Is it impossible to get some utf-8 support in ToME ? In monster/item descriptions and such, not in map/main view?
Or some way to get non-latin characters here?
