How? Since you can not register utf-8 channels on undernet.
I really doubt that is the case. (It actually isn't even possible to block UTF-8 channel names while allowing codepage channel names if you understand how UTF-8 works.) Have you tried registering a channel that was UTF-8? If not, who said that you can't?
I guess it is possible if you know how to input the channelname in utf-8 format on the webpage where you register channels. But we both know that most users are not bright enough to understand how to do that. If they type a channel name they expect to have that channel registered, and then when they type the very same channel name in mIRC they will join the wrong channel. because their browser type it in one format, and mIRC in another.
