How do I get the × html entity?
In a comment, SFAIK, you don't. How posts are written and how comments are written are not consistent. Though if you're willing to rely on people defaulting to the correct encoding, you could always just paste the character in directly...
This site has proper Content-Type headers, so it should work fine in all sane browsers.

It worked! (At least for me.)
