Language Support in Channel Names

The new font for channel names doesn't support a lot of languages.

Russian, the 8th most commonly spoken language on the earth, isn't supported by the font. Just for an example, here is a channel named "русский-язык-russian-language"

another not too rare language is Vietnamese, 21st most commonly spoken, even though it is using the Latin alphabet, that doesn't stop the special characters from looking wrong.
as one can clearly tell, this isn't how these are supposed to look.
