Warning : 3719 'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release. Please consider using UTF8MB4 in order to be unambiguous.

The exception is that in table definitions, utf8 is used because MySQL converts instances of utf8mb3 specified in such definitions to utf8, which is an alias for utf8mb3. One advantage of converting from utf8mb3 to utf8mb4 is that this enables applications to use supplementary characters.A warning that caught my eye in MySQL 8 (8.0.21) was this one on Unicode with the utf8 character code: Warning (code 3719): 'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release. Please consider using UTF8MB4 in order to be unambiguous.Longer answer: Zabbix wants 'utf8' with MySQL and MariaDB, and for MySQL (and MariaDB, for compatibility with MySQL), the 'utf8' character set doesn't mean true 'UTF-8'.

Some data type also allows you to pass an optional parameter to control the output. Let's see some examples! Examples Of MySQL CONVERT ...

The problem is that the information_schema that is queried for table information uses UTF8, which is an an alias of UTF8MB3. MySQL has introduced a warning from MySQL 8 to encourage you to use UTF8MB4 explicitly. inspectdb cannot deal with that warning. I appreciate this may be regarded as a MySQL feature/bug.
