That sounds like a good plan to me. Personally I'd want a
memcmp()-based collation implementation available, so that people who
don't care about sorting anything beyond 7-bit ASCII don't need to pay
a lot of overhead.
We have seen over and over that strcoll() is depressingly slow in some
locales (at least on some platforms). Do you have any feeling for the
real-world performance of the Unicode algorithm?
