To be correct, the FTP cannot handle any name containing ( %x00-1F /
%x7F-FF ).

The use of UTF-8 encoding for non-ASCII characters is MARGINALLY workable;
the chances of failure are low enough that there seems little reason to
worry about it as an implementor, but from a protocol level the current
specifications are insufficient to ensure it will work without error.
