Emoji are smileys or ideograms originally used in Japanese electronic messages and webpages. Emoji means "picture" (e) plus "character" (moji).
The emoji dictionary is a fun project and creates a community to get people fluent in emoji. You can promote your own emoji translations and decrypt messages you get.
The page itself works on all available browsers on Android and iPhone, even though support for emoji in todays operating systems and mobile devices is not fully available.
A big thank you to the guys at EmojiOne who designed amazingly cool emoji symbols and a library to bring it to all of you - be it emojis on the PC, Android, iPhone or any other device.
