Feature Request : Support for Cyrillic languages

[Gribovoy29]

Hello, Love the theme, but the only issue I have is that the font used does not work with languages that use Cyrillic. While I can change the font for the menus, I cannot do the same for the Now Playing screen. It's not a giant problem, but a bit annoying

Anyway, thank you for making this great theme. Might be the only stylish theme on the Rockbox
