I understand what you are saying, however I think it is important that IRC makes the transition to UTF-8. If the new version of mIRC adds support for codepages then IRC users will continue to be stuck with codepages, along with their limitations and broken support when mixed with other encodings, for a very long time. IRC needs to move forward. Hopefully by making the new version of mIRC use UTF-8 consistently, and with other clients doing the same, IRC as a whole will slowly converge towards UTF-8 as standard.
