MySQL tables should use utf8mb4 character set — at Initial Version

Historically, the MySQL utf8 character set has only supported the first character plane of UTF-8. With MySQL 5.5.3, it now supports the entire character plane, using the utf8mb4 character set. This character set is 100% backwards compatible, and does not require more space than utf8 for characters that fall within the utf8 set, only using an extra byte for characters outside of the utf8 set.
