Hello Alex, thanks for your post, much appreciated.

If I recall correctly, at one time Mac IRC clients were unable to display reverse text and so chose to display control code 22 as italics instead of reverse. It may be that subsequent Mac IRC clients assumed that control code 22 was meant to be interpreted as italics. That is just a guess however.

I am fairly sure that mIRC has interpreted control code 22 as reverse since 1995. I hope it will not be too much trouble to synchronize control codes. If you have any questions or would like to discuss anything else I can be reached at khaled@mirc.com.
