emoji4j

[WARNING]: This project is not actively being maintainted. You may use vdurmont/emoji-java as an alternative.

Java library to convert short codes, html entities to emojis and vice-versa. Also supports parsing emoticons, surrogate html entities.

Inspired by vdurmont/emoji-java, emoji4j adds more goodies and helpers to deal with emojis. The emoji data is based on the database from github/gemoji and ASCII emoticons data from wooorm/emoticon.
