Changing name in Amnesia

[teylin]

Hello!
I translated the visual novel  (Amnesia: Memories) into Russian, I already made everything, exept naming screen.  

I ran into a problem... It's impossible to write the name of the heroine in Russian.

Spoiler

Can somebody help me to add russian language support? 

I already tried to make changes in some files, but it didn't help..
