This is something that is on our plans for future support.

Currently, the IIS FTP server has limited support for multi-byte character
set (MBCS) sequences in file names, and requires that the code-page on
client and server be exactly the same. Unfortunately, there may be
collisions between valid MBCS names in some code-pages, and either FTP
special characters or file-system special characters, so those characters
may get translated or removed even if you are using the same code-page at
client and server.

There is an RFC (RFC 2640) that describes using the UTF-8 encoding to get
around that - if you make your FTP client use UTF encoding, it may not make
the file names readable in an Explorer window local to the server, but to
another client, the file name will be exactly as you used it when uploading.
