Some fonts show up XXXX out?

It seems like the characters are in Unicode format, which might not be fully supported by your current browser or device.

I get that with specialty fonts that do not have a corresponding character to the usual ABC, etc.

Weirdly enough this happens to me as well with regular serif fonts as well, not just special characters.
