Pre-9.1 levenshtein is ASCII-only, and I think some of the other stuff
in contrib/fuzzystrmatch still is.  We had to work pretty hard to
avoid a massive performance loss when we made it multi-byte aware, and
IIRC there is still a pretty significant performance loss if any
multibyte characters are actually present.  But at least now it
doesn't return totally bogus answers.

So I have some sympathy with the OP's desire not to burden himself
with the non-ASCII case if he doesn't need it for his application, but
I also agree with your point that we probably wouldn't accept code
into contrib that doesn't.
