Bug:

Early Mac OS X (10.0-10.4.?) had the limitation up to 255 Byte. Current implementation is: volcharset -> UTF16-MAC -> truncated 255 UTF8-MAC

Recent Mac OS X (10.4.?-) don't have this limitation. Desirable implementation is: volcharset -> truncated 510 UTF16-MAC -> UTF8-MAC

Note

with utf8 filename not always round trip

filename   mac filename too long or first chars if unmatchable chars.
uname      unix filename
id         file/folder ID or 0
