Doh, you're right ... but on third thought, what happens with a pattern
containing "%_"?  If % tries to advance bytewise then we'll be trying to
apply NextChar in the middle of a data character, and bad things ensue.

I think we need to go back to the scheme with SB_ and MB_ variants and
no special case for UTF8.
