As Roozbeh noted, Unicode 6.0 came out yesterday. Somewhat fittingly (given it having been National Coming Out Day), it adds
U+1F46C 👬 TWO MEN HOLDING HANDS and
U+1F46D 👭 TWO WOMEN HOLDING HANDS
Unfortunately most people will probably be looking at small boxes with numbers in there for a while yet, which is probably a wonderful metaphor but I'm not quite sure for what.
I love Unicode. I love that it lets me produce correct typography without having to resort to ΤΕΧ. I love that it allows for hilarity like Zalgo and years of entertainment in searching for the limits of the LCA conference badge rendering. I'm thrilled that a poorly managed introduction of IDNs let me get away with things like www.☭.net, and that nobody's got around to taking it away from me yet. And U+1F64C 🙌 PERSON RAISING BOTH HANDS IN CELEBRATION is going to be a core part of my IRC character set the moment I get a compose map that includes compose+\+o+/. But I also love little things like having the typographical freedom to express whatever kind of relationship I choose to.
Well, providing that it's between two adults. Maybe 6.1 should add combining variants?
