version is less than 5.5.3, the version upgrade is done first, and then the corresponding data type is changed to the UTF8MB4 type. If you are using a connector/j connection database, you need to change the encoding format to UTF8MB4 (set character_set_server=utf8mb4 in the Connection config) in the configuration. 2) Custom filter rules that filter or convert the four-byte UTF-8 characters that appear in the text to a custom type.Transferred from: http://blog.csdn.net/fuxuejun/article/details/2

Set_results,character_set_server are modified to UTF8MB4, but I did not do this step, but also normal, so it may be that this step is superfluous, if you need to change, follow the instructions below to make changes.3 Modifying the MySQL configuration file my.cnf (Windows My.ini)MY.CNF generally in the etc/mysql/my.cnf position. When you find it, add the following three sections:[Client]Default-character-set = Utf8mb4[MySQL]Default-character-set = Utf8mb4[Mysqld]Character-set-client-handshake =

the MySQL 5.5.3. Solution: 1) using the UTF8MB4 data type To use this strategy, if the MySQL version is less than 5.5.3, the version upgrade is done first, and then the corresponding data type is changed to the UTF8MB4 type. If you are using a connector/j connection database, you need to change the encoding format to UTF8MB4 (set character_set_server=utf8mb4 in the Connection config) in the configuration. 2) Custom filter rules that filter or convert the four-byte UTF-8 characters that appear

First, this is the coding problem.The solution is to erase the data and create one.Today, after inserting a piece of data, we find that the data inserted in the database is garbled, and then we look at the MySQL code.Show variables Likem '%character% ', and then sure enough in the client is Latin, then go find tutorials http://blog.csdn.net/crave_shy/article/details/23345869Then follow the tutorial to modify the database encoding, and then, in the execution of a program, there is the error above
