I like this much better (I was just trying to be consistent with the old
interface), but this is certainly easier to use.

I don't think it will be too bad. Currently only ~260 variant selectors
are reserved and less than 10 are actually defined.
The only questionable one is FT_Get_Chars_Of_Variant, but even here I
don't think there will be any huge arrays -- my understanding is that
even Adobe-Japan-1 has only 1222 characters with multiple variants.
