Character Sets

GaussDB allows you to specify the following character sets for databases, schemas, tables, or columns.

**Table 1** Character sets
MySQL	GaussDB
utf8mb4	Supported.
gbk	Supported.
gb18030	Supported.

Currently, GaussDB does not perform strict encoding logic verification on invalid characters that do not belong to the current character set. As a result, such invalid characters may be successfully entered. However, an error is reported during verification in MySQL.
