MySQL Error 2074: Invalid Multi-byte Client Charset
Description
This error indicates that the MySQL client is attempting to connect using a character set that has a minimum character length greater than 1 byte, which is not permitted for client connections. This typically occurs when client applications, drivers, or system environment variables are configured with such an incompatible character set.
Error Message
'%s' character set is having more than 1 byte minimum character length, which cannot be used as a client character set. Please use any of the single byte minimum ones, e.g. utf8mb4, latin1 etc.
Known Causes
3 known causesClient Application Configuration
The client application or its database driver is explicitly configured to use a character set (e.g., `utf16`, `utf32`) that has a minimum character length greater than 1 byte for the connection.
Environment Variable Mismatch
System environment variables (such as `LANG` or `LC_ALL`) are set to a locale that implies a multi-byte character set incompatible with MySQL client connections.
Incorrect Connection String
The connection string or command-line parameters passed to the MySQL client explicitly specify a character set that has a minimum length greater than 1 byte.
