However, an ftp server is different. It might start up with an empty
folder, and receive *all* of its files through upload. Then it can
certainly know what encoding the file names have on disk. It *could*
also support operation on pre-existing files, e.g. by providing a
configuration directive telling the encoding of the file names, or
by ignoring all file names that are not encoded in UTF-8.

I don't see how starting with an empty directory helps.  The filename
comes from the client, and the FTP server can't know what the actual
encoding of that filename is.

Exactly, only client can do filename conversion. May be ftplib could be extended to know encoding on filenames on local and remote system based on some user settings. May be ftplib could use UTF-8 or UCS-2/4 to store internally filename but direct conversion is may be faster. It the last case filename is a byte sequence.
