Connecting to a domain with scandic name (in this case
including ä ä järvinen.info) caused error:
"Cannot list directory. java.net.UnkownHostException:
ftp.järvinen.info"
Domain works on firefox and I can connect to it with
that and some ftp -programs.
I'm sorry that I can't give an account to that server
for testing, but I think this is just some sort of
validation or encoding bug.
ftp.xn--jrvinen-5wa.info works though debug print included

Any movement on this bug in the intervening 4+ years? If not, I suggest closing it, as there's not submitter attached. If someone has this issue currently, it's time to open a new bug.
