Actually, it’s in the subject. There are very few fonts that support Cyrillic symbols and actually work. Googlefonts have 68 Cyrillic fonts, but if you use, say, Open Sans, then it renders words in English fine, and for Russian it uses Times New Roman (I guess). It’s the same in Nirvana as well. Could you, please, check and fix?
Most of the bundled font files don’t include extended character sets. If you need them, use Google fonts (you can use the same font name as one that’s already bundled, filling in the Google font identifier field will make the theme load the font from Google). Make sure to include the needed character set(s) in the identifier.

Would you, please, show how exactly I should fill in, for example, for Open Sans to get both Latin and Cyrillic sets in my site? Before I only filled in Open Sans, and it did not work for Cyrillic.
