Look at the picture, when the mariadb configuration, has been in use for init_connect='SET collation_connection=utf8_unicode_ci', you can see the mysql client according to the character SET is utf8 - unicode - ci, but the execution is the size of the command is wrong, prompt utf8 - general - ci and utf8 - the unicode character SET - ci, and Heidi client use the same query command, this time found out the collation - the connection of the character SET is utf8mb4 - general - ci, should Heidi is right, not an error,
What do I do now?
