I mean Internationalized Domain Name System by i-DNS.net International. I use iClient v7.0 and WinGate 6.1.2 (Build 1094).
With WinGate I can't use cyrillic domain names. But when I do not use WinGate proxy (and use direct Internet connection to my ISP) cyrillic domain names work OK.
E.g. error message: Host name lookup for '%EF%F0%E5%E7%E8%E4%E5%ED%F2.%EE%F0%E3' failed
