My attempt at this is the Encode::Locale module[1].  This also tries to handle
the fact that on Windows the console "locale" might be different and that the
"locale" to use for file names have divergent rules.

That module has also accumulated some hacks to deal with mappings where there
isn't the strait correspondence between what langinfo() returns and the encoding
names Encode knows about.
