Mac OS X file name encoding problem

Hi all, I have a problem with a script when it is runs on a Mac OS X environment. a part of this script simply takes an upoloaded temporary file and writes it on the local system using ftp functions. something like: $filename = $TheNameToAssignToTheFile; $ftps = ftp_connect($ftpaddress); $ris = ftp_login($ftps,$ftpuser,$ftppassword); $fi = fopen($_FILES['file']['tmp_name'],"rb"); ftp_fput($ftps,$filename,$fi,FTP_BINARY); fclose($fi); The problem appears when $filename contains special characters, like accented chars, on Mac OS X the ftp_fput function returns me an error. I thinked that the problem could depend on the filesystem encoding, that on Mac OS X is Unicode, so I tryied this before: $filename = utf8_encode($filename); this way I have no more an error, but the file name of the uploaded file results anyway corrupted with strange chars. Any help is greatly appreciated,
