        I think that the iso8859-1 character set (and possibly others
in that group) maintain correct sorting order within a particular
locale. So, if iso8859-1 is an acceptable subset, all you need to do
is to convert from utf-8 to iso8859-1, and do the sorting on that.

        Further, I think that you can use strcoll() to sort strings so
that "très" and "tres" are treated as identical.
