AnswerTo support full Unicode in MySQL, the utf8mb4 encoding support is required.
Upgrade/install MySQL Server 5.5.3 or higher. MySQL 5.5.3 adds support for utf8mb4 character set which is required for some Unicode characters which use 4 bytes.
Upgrade/install MySQL driver 5.3.11 or higher.
MySQL Connector/ODBC 5.3.11 release notes stated "The Unicode version now uses the utf8mb4 character set as a transport character set between the MySQL server and the ODBC driver.
Set the encoding to utf8mb4 in MySQL server.
Please follow the instructions in How to support full Unicode in MySQL databases
