It shows fine here (unicode that appears as an O made of of "dots").
In any case, currently unicode is only partially supported and you will often have to use $utfencode() in order to get some things to display correctly. This happens mainly when specific characters are used in combination with unicode characters. I forget the exact characters that cause this effect, but it's something like $chr(127) to $chr(255). Your degree symbol and overline (¯) are the likely culprits in your example. If you remove them, you probably won't have a problem anymore. Of course, that does ruin your "art" ... much easier just to $utfencode() it in the alias. I believe the reason for this is that those characters aren't technically supported in unicode and you can't mix unicode and non-unicode, so mIRC chooses to display it all as ascii if anything that isn't supported in unicode is on the line. $utfencode() gets around this.
That said, the next version of mIRC will support unicode and you shouldn't have this issue anymore if you upgrade to the new version when it comes out.
