[Samsung Galaxy Nexus] starrwulfe:
What you guys are seeing is actual Unicode 6.1 support finally baked into Android. For us living in Japan, our carriers always added an extra font pack into "Droid Sans Fallback" to handle emoji. Apple stuck emoji in there to be able to sell iPhones here in Japan. Now with Unicode standardisation, we can finally get Emoji fonts even on our PC.

try looking at the following on your Jellybean (or iOS) device... (you may have to copy/paste into notepad or something to get them to show up properly.) These are straight from the Unicode 6.0 character maps--all you need is a font that will support them.

There's tons more. Check out http://www.alanwood.net/unicode/index.html for info.

If you want to backport the emojis, then search for "emoji droidsansfallback.ttf" on El Goog, or better yet, someone post the DroidsansFallback from the new Jellybean release so we can give it a shakedown, yeah? ��

Here's what they look like BTW.

Also here they are on Windows Phone for comparison...

The reason they're monocromatic is they are meant to be just like another font in your system. Apple just chose to use PNGs for their mapping, but it takes up a little more space in the system.
