Adding Emoji to Ubuntu
From the eye-candy dept. (7805) (0) by Luis
You can add Emoji fonts to your Ubuntu system by simply doing:
sudo apt-get install ttf-ancient-fonts
To verify, go to the Emoji page on Wikipedia. The fonts are not as cool looking as the ones on your iOS devices, but at least you won't be missing on the fun while browsing Twitter 😊.
You can follow some of the bugs in launchpad reporting this missing functionality in Ubuntu.
