There were GNU IPR concerns with Bruno's code, whereas my little hacks
are all "public domain -- share and enjoy".

I added all those you mentioned, but also note that we are not
interested in Debian/Linux here at all, because it has already
a fully operational nl_langinfo(CODESET). We only worry about the
legacy systems like *BSD, which don't have it yet.

Are you really talking about existing practice on systems without
nl_langinfo()?

I know about HP-UX, but I think that has nl_langinfo() anyway, so again
no problem here. Please correct me if I'm wrong.

NEWS:

I have just also written a normalization function for the output of
nl_langinfo(CODETSET) on different platforms. I tested it only on
Linux and Solaris so far, so please try it on any other platform you
have access too. Test instructions are in the source code.
