Gem Version Build Status Dependency Status Coverage Status

Ruby library providing low level operations for dealing with Emoji glyphs in the Unicode standard. :cool:

EmojiData is like a swiss-army knife for dealing with Emoji encoding issues. If all you need to do is translate :poop: into :poop:, then there are plenty of other libs out there that will probably do what you want. But once you are dealing with Emoji as a fundamental part of your application, and you start to realize the nightmare of doublebyte encoding or variants, then this library may be your new best friend. :raised_hands:

EmojiData is used in production by Emojitracker.com to parse well over 100M+ emoji glyphs daily. :dizzy:

Don't like Ruby? This library has also now been ported to NodeJS and Elixir.

Installation

Add this line to your application's Gemfile:

gem 'emoji_data'

And then execute:

$ bundle

Or install it yourself as:

$ gem install emoji_data

Currently requires RUBY_VERSION >= 1.9.3.
