FTP adapter file transfer in ASCII mode

Hi all,

I'm using BTS2006 and has configured the FTP adapter to transfer files in 
ASCII mode to AS400. My problem is that files with swedish characters
(Å,Ä,Ö) 
can't be transfered. If i 'put' files with my ftp client there's no
problem 
even with files including swedish chars...

I've tested different codepages for the source flatfile schema 
(UTF-8(65001), Western European(1252) and ASCII) with the same result.

Any ideas how i can solve my problem?
TIA
