Character Set Configuration

Currently, TiDB only supports the utf8 character set, which is the equivalent to utf8mb4 in MySQL. Since MySQL 5.7 defaults to latin1, this difference is documented under default differences between TiDB and MySQL.

For more information, see Character Set Configuration in MySQL.

"Character Set Configuration" was last updated Sep 10 2018: sql: Clarify default character-set is utf8 (#609) (d2229f3)
