I see you found it, but note that it's _not_ a spurious UTF-8
character: it's a right-to-left mark, ans is a perfectly ok UTF-8 code
point.

If you need a subset of the UTF-8 character set, you want to make sure
you have some sort of constraint in your application or your database
that prevents insertion of anything at all in UTF-8.  This is a need
people often forget when working in an internationalized setting,
because there's a lot of crap that comes from the client side in a
UTF-8 setting that might not come in other settings (like LATIN1).

Best,
