Thanks for the feedback everyone, this issue has been fixed in the upcoming release. I have been working on converting mIRC to a full unicode application, a major project that has taken the better part of a year. The unicode version of mIRC has been "almost" ready for a beta release for some time, so it did not make sense to release a new version of mIRC just for this one fix. I will be posting a public beta announcement the moment the new version is ready for use.
