SET CHARACTER SET
Syntax
SET {CHARACTER SET | CHARSET} {charset_name | DEFAULT}
Description
Sets the character_set_client and character_set_results session system variables to the specified character set and collation_connection to the value of collation_database, which implicitly sets character_set_connection to the value of character_set_database.
This maps all strings sent between the current client and the server with the given mapping.
