What happened:
The Russian language is not the correct font.
What actually happened was:
When selecting the Russian language is why it is not correct Unicode why the small letters. Small letters annoying because 1) not visible, 2) very difficult to see if a small interface. Well, that's all.
P.S A fat font, which I found in the Internet, I think this is a very good font to change it.
P.P.S If you look and how to create a resource pack. the letters on half is not visible.
