Scandinavian letters äåö missing in 4.0.2 (FTP)?

Very good program but shouldn't it accept scandinavian letters ä, ö and å too? For example Wed*ding Night is hääyö in Finnish. If I had a Word document hääyö.doc, it would be hy.doc after FTP transfer.

Please try following: Switch your session to SFTP, go to SFTP tab, select "off" for "server does not use utf-8" and switch the session back to FTP.
