I've heard various ideas such as limiting it only after mods have expended their points (this will require implementing a cooldown to prevent a user from getting points again too soon). I want to hear your feedback, and I'll roll together something for the next major update of the site. Leave your comments
5. Everyone's always bitching about lack of Unicode support, and others have said in the past that the reason it's mostly disabled is because of trolls using right-to-left switches, non-breaking spaces, and other methods to disrupt the page layout, and so I guess it's filtered out at posting time. Whitelists are sort of a non-starter given just how big the Unicode space is, so why not just open up clear Unicode access to those who can be trusted not to abuse it?
That may be true on the other site, where every Unicode character not on a very narrow whitelist is filtered out, but from the behaviour seen here, I think it's more of a problem with Slashcode interpreting the UTF8 byte stream differently than the browser encoded it. If using numeric entities, you can post almost unlimited Unicode (directionality markers seem to be filtered out, however).
