We've added support for autocompleting native Emoji (Unicode 8) inside any Remarkup text area in Phabricator. We've also fixed a few issues with Emoji rendering in Windows 10, now enabling full color inline Emojis. If you use Chrome on Linux, you can add extensions to help enable full color emoji or enjoy the simpler life with the standard line art your OS already ships. Adding Emoji color commentary to your code reviews and tasks has never been easier. The autocomplete typeahead will appear with any : + letter key combination and help you quickly add emotion to your comments. We'll insert the raw unicode with no special markup.

We'll continue to refine the typeahead as well as add a proper picker to the Remarkup bar. Any questions, issues, or feedback, please see https://secure.phabricator.com/T12139.
