But it doesn't show up in many unicode tables, so either it's new or non-standard.

Your Unicode tables must be out-of-date. Emoji's been in Unicode for a while now.
I'd been using http://www.fileformat.info/info/unicode/char/search.htm but I'll have to find something else if it's out of date.
I have a Windows Phone 8 beta, and the built-in keyboard now suggests related emoji as you're typing. It's not as obtrusive as it might sound, and I think it's fun even though I never use them.
edit: Oh, for shame, HN doesn't unicode that quite right.
