I think this may be another facet of something we were already aware of,
which is that the UTF8 locales on OS X pretty much suck. It's fairly
clear that Apple has put no effort into achieving more than minimal
standards compliance for those. Sorting doesn't work as expected in
those locales, for example.
Still, that's reality, and any proposal to rely on strxfrm is going to
have to deal with it :-(
