When I writing in editing mode two fonts are mixed together and it produce ugly view. Only latin charachters are supported... Maybe we can choose something from Google Fonts?

Hey Alex, thanks for posting here. What international characters are you missing from the font in use? I'll look into it and see if I can find a good-looking font with the letters you are looking for. Thanks!
