# All about Emojis
Perfect Publisher, Full Unicode, and Emojis 😎 support for Joomla!
Since Joomla! 3.5 a new feature has been included: Full Unicode (utf8mb4) support.
The difference between utf8 and utf8mb4 is that the former can only store 3-byte characters, while the latter can store 4-byte characters. In Unicode terms, utf8 can only store characters in the Basic Multilingual Plane, while utf8mb4 can store any Unicode character. This greatly expands the language usability of Joomla!, especially in countries that use Han character sets. Unicode isn’t without its problems, but it’s the best option available.
Emojis are the main feature we love on Facebook, Twitter, WhatsApp, and every possible social network. Since the release of Joomla! 3.5, the full range of expressions are available for social publishing from Joomla! sites.
