Hi there, Seven years later :-), I'm just sending this e-mail to confirm that this patch still works and fixes the issue. It can be found (applying cleanly against the latest version of this package) here: https://raw.githubusercontent.com/marado/netkit-telnet-ssl/master/netkit-telnet-ssl-0.17.41%2B0.2/debian/patches/700-fix_UTF8.diff
