Run the following command under MySQL command line client to view the MySQL character set:

Character Set support has two aspects: Character Set and collation ). The support for character sets is refined to four levels: Server, database, table, and connection ).
You can run the following two commands to view the character set and sorting method settings of the system:
Mysql> show variables like 'character _ SET _ % ';
