Character set results null

If you specify a character set 18th engineer brigade patch that is valid but not permitted as a client character set, the server returns an error: shell mysql -default-character-setucs (42000 Variable 'character_set_client' can't be set to the value of 'ucs2' If you specify a character set that the client.

It is unnecessary to set character_set_connection explicitly.

For example, utf8 and utf-8 map to utf8mb4, and ucs2 is not supported as a connection character set, so it maps to the compiled-in default.Suppose that the server is configured to use latin1 and latin1_swedish_ci as its defaults, and that it does not recognize gb18030 as a valid character set.A client that specifies -default-character-setutf8mb4 is able to connect to the server.This occurs because the server cannot satisfy the client character set request and falls back to its defaults.Connect-Time Error Handling Some character sets cannot be used as the client character set; see Impermissible Client Character Sets.To determine this, the server uses the character_set_connection and collation_connection system variables: What character set should the server translate query results to before shipping them back to the client?On which side I can solve question?Mysql show session variables like 'collation_connection Variable_name Value collation_connection latin1_swedish_ci You can see that the connection system variables have been set to reflect a character set and collation of latin1 and latin1_swedish_ci.This occurs, for example, when a MySQL.0 client wants to connect to a MySQL.7 server using utf8mb4 as the client character set.It is unnecessary to set that collation explicitly.

The same problem occurs in a more subtle context: When the client tells the server to use a character set that the server recognizes, but the default collation for that character set on the client side is not known on the server side.
