Special characters don't work correctly
After Japanese support was added in #9, I've noticed that the renderer doesn't handle special characters correctly.
Example: https://invidget.switchblade.xyz/discord-developers?language=ja

Discord seems to use Hiragino Sans for japanese. We could try to use that as a fallaback for characters that Whitney doens't support.
But does it affect all dialects (Hiragana, Katakana and Kanji)? @Flicksie
Discord seems to use a mix of hiragana and kanji (which should have been displayed in the screenshot above), so I guess it should affect Katakana too.
Ah, ight. PS: that workaround should also work for server names
Yeah, I'll probably end up implementing some sort of global font fallback for all the text we render
in #41 affect this issue.
in Discord css. it classified by region.
but How about use Noto Sans for these? i know it haven't in Discord Client but I think It covered.
Noto Sans doesn't (at least) cover the Korean language, I think.
It could cover other ones, though, but I didn't test it. Most probably we would have to implement Apple SD Gothic Neo, Hiragino Sans, YaHei New and JhengHei.
