This sounds like a tough way to do this to me, but it may be the only
way.  What if we just take the code for doing strcoll out of glibc and
write utf8_strcoll?  It would just use all the locale specific
information we can find in glibc.

I'm not sure how glibc is set up to be expansible with respect to things
like strcoll, but we could take a look at doing it similarly.

Thanks,
