DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hi, my DNS-313 works fine after re-installing software. The unit is in my home. But when I connect from my computer at work, via AceFTP or Ipswitch FTP, the folder names and file names are wrong-spelled when norwegian letters are being used. Some adviced to change settings in FTP-programme to UTF-8, but I cannot find this option (only a lot of other servertypes like UNIX etc).

Anyone have a suggestion? Thanks in advance!
