Add emoji support to the new phone text messages & bleeter (or, anywhere, really)

[Pazz]

I tried to add a sobbing emoji () to a Bleet. It turned into five diamonds (◆◆◆◆◆) instead. It's not a big deal in the larger scheme of things, but I do think it takes away from the experience, no matter how minor, and I think it would add a lot to be able to use emojis in Bleeter, in text messages, and generally, on the phone, where it makes sense.
