Charsets are registered by IANA.

Of course, it doesn't particularly help in this case because filesystems
for the most part (*) just care about octets and don't interpret them. The
filesystem isn't going to tell you an encoding scheme for a name.

(*) Some filesystems do for example case folding or unicode normalizations.
However for opening a file pretty much the only guarantee is that the
octets you got from a directory listing of filesystem can be used to open
the file.
