Just for record, I'm not in favour of a transparent, locale
dependant file name transcoding. IMO having file names change
with user locale would be an administrative madness.

My primary aim is to have a reasonable way to handle file systems
which use Unicode as it's internal file name character set. UTF8
is clearly one of the best choices here, since it's the only standard
UNIX-compatible way to handle full Unicode range.

I stay fully content with FFS/ext2fs/lfs to be file name encoding
