thanks..

You actually can copy/paste from the web if you set up your multibyte settings correctly and either use font-linking or a font that supports the characters. Also, the next mIRC is supposed to include full unicode support, so you'll be able to copy/paste even more easily at that point.

For multibyte settings, these work fine for me:

Alt-O > IRC > Messages

Check multibyte editbox, UTF-8 display, Font linking, and ANSI codes.

Note that there may be other combinations that also work, but that works fine for copy/paste from a browser.

these are already checked the thing is yep i can copy paste but if i use this ★ it goes to a ? when i enter it. but then for the same character im trying ★ and it shows as the black star when u enter it.. btw im on windows if that helps..

That specific character may not translate well with font linking. You would need to use a font that can display it. Beyond that, all you can do is use the ascii combination to display it or wait until the next mIRC.
