rsync - Apr 2003 - rsync files and directories with german umlauts ?

Hello,

i need to sync mounted Windows NT Filesystems with rsync.
I mount the filesystems with "mount -t smbfs -o ...".
All works fine, but no File or Directory with non iso-latin1 character (in
example german umlauts like ?,?,?) will be sync ...

Because it's urgent and important for me, i need help for this problem ...

Thank's a lot
Jens Bruns
