hi all i would like to sync a directory tree on a os x server to my linux "backup" server. in generall it works, but i've asserted that folders and files containg a letter with a diacritical mark (for example: ?,?,?) cause problems. they are beeing transefered but show up with a messed filname on my linx server. has someone an idea how to solve this problem? brest regards sam
