Please clarify what issue you're experiencing and I'll gladly assist you in solving it. Are you referring to the display of the Russian font (compared to our new font face for headers)?
Yes, please use the Cyrillic script.
Unfortunately, the new font we're using doesn't support Cyrillic script. Please try to type "Google" using the Cyrillic script and let me know if the font looks just as the rest of the text.
