Interesting! Indeed, just tried on an old Linux Redhat system... BTW,
that's pretty odd for a unix system. "ls -l" sorts aaa before BBB, I've
never seen the likes of it! Call me old fashion if you like ;-)
Still, as you say, FreeBSD does it capital letters first, and does not
handle unicode locales' collation, so I need an alternative. Perhaps the
best way would be to inject ICU into BSD instead :-)
