Well, the point is, to my knowledge no ircd (atleast not dalnet and undernet), support upper and lower cases for none a-z chars.
See, that's the point right there. The ircds are the ones who control that. Not mIRC. Someone can just as easily create two channels with different capitalization in other clients. It has nothing to do with mIRC and again, it isn't mIRC's job to force that issue. If it did and other clients let people name the channels whatever they wanted, then no one using mIRC could enter the channels made by the other clients.
And, like what has been mentioned, mIRC is definitely not the first to add UTF8 support.
What it comes down to is that Unicode is here and it's here to stay. It has been around for around a decade. Ircds have had plenty of time to add support and haven't bothered. That isn't mIRC's fault. mIRC and other clients can't just sit around stagnant for decades just because ircds are lazy. So, because it's here to stay, it would be smart for anyone who has such concerns about capitalization to name their channels with all lowercase (as that will be how most people try joining the channels anyhow). And if they don't want someone to create a channel with a similar name, they will need to create it themselves. Once again, this is not mIRC's job. It is up to the ircds to support or not support those kinds of channels and up to the channel owner(s) to handle the situation in a way that makes the most sense for their situation.
