There are other places things can go wrong, of course.  If
you use STRING-{SEARCH,MATCH}-POSITIONS, in code that's not
utf8-aware, and any of the match positions come after wide
characters in the string, then it will break if some other
egg has loaded utf8.

This just makes me sad.  The whole concept of referencing
strings by index is broken.
