Since strcoll() assigns meanings to strings, it would obviously need
to decode the UTF-8 characters; except, of course, in the "C" locale
(where sorting is defined to be in binary order) since UTF-8 binary
order is identical to Unicode binary order (fortunately... it would be
very confusing to know what the "C" locale should do, otherwise.)
