Unlike its utf8 encoding, MySQL’s utf8mb4 encoding offers full Unicode support (including four-byte UTF-8-encoded symbols).

The utf8mb4 character set is useful because nowadays we need support for storing not only language characters but also symbols, newly introduced emojis, and so on.

utf8mb4 has been available since MySQL 5.5.3 (released March 2010).

More information about the utf8mb4 character set may be found on the official MySQL Documentation.
