Provide «alphabet» in separate files.

I think you shoul move the part where you assigning visual representations of letter to separate file in specific folder and then autoload it.
This mechanism would be usefull if somebody uses non-latin characters or some specific unicode symbols. He could just add new file with this letters. And filesize of your main py file would remain unchanged.

Thanks for your feedback. Regexp sanitizing non-latin characters in the code so there's no problem about non-latin characters actually. And yes, you're right about filesize of py file. I'll seperate them as soon as possible.
