The character set named utf8 uses a maximum of three bytes per character and contains only BMP characters. As of MySQL 5.5.3, the utf8mb4 character set uses a maximum of four bytes per character supports supplemental characters.
Characters such as emoticons need the extended encoding. DiscourseDB should therefore use utf8mb4 by default
