I have problems with special german characters in filenames and Rsync.

I rsync from OES SP2 (NSS) ---> NW6.5SP5 (NSS)
Rsync works, I can open all files on NW6.5SP5 - but I loose the german
filename-characters on the target.

I tried with different locale settings on linux site (de_DE.ISO-8859-1,
de_DE.UTF-8) and different codepages (437, 850) on netware site --> no

Any ideas?
