utf-8-hfs is part of ucs-normalize and IIRC works on all platforms.
utf-8-nfd is the old one which only existed on the ns implementation,
and didn't work for encoding anyway (which was the cause of the
completion bug).

AIUI utf-8-mac is regular UTF-8 with CR line endings and is intended for
use with files created on *classic* MacOS, and should not be used for
this purpose.
