Font 'SourceSansProRegular' in Russian language

[rost]

"Source Sans Pro Regular" looks terrible in Russian language.
Change the font to Arial, I checked, it looks much better!

And how can I help with the translation into Russian?
Lobby in Russian is not a Лобби!
Try to make the voting system for the controversial and complex translations, such as in whatsapp!

p.s. But on the other hand, we can not waste time on the translation, I believe that everything has to be standardized and in English. )))
