Well, that depends on whether you're going to make a special typlen
value for *just* UTF-8, which would probably cost about the same. Or
allow any type to have it's own Datum length function, which would be
very expensive. Calling user-defined functions is not cheap.

I don't think making a special typlen value just for a type that can
store a single UTF-8 character is smart. I just can't see enough use to
make it worth it.

Have a nice day,
