This will return the first non-empty name, is that really what you want?
Checking for the preferred language and returning that if set (and falling back
on the first non-empty_ seems like a better idea.

Another option would be to always return all of the names.

Yes, that's intended. I hope in future this will be replaces with a simple
SKTypeface.getFamilyName() call, which is currently bogus:
