Description
Describe the bug
Escaping bytes with _binary prefix causes error on MySQL.
SqlAlchemy doc mentions it:
https://docs.sqlalchemy.org/en/20/dialects/mysql.html#dealing-with-binary-data-warnings-and-unicode
Also pymysql takes _binary_prefix as optional parameter with default value False and adds _binary prefix if true.
PyMySQL's behaviour should be more appropriate imho.
To Reproduce
Have a SqlAlchemy Model with JSON column and try to create a new record.
Expected behavior
Should able to create record.
Logs/tracebacks
OperationalError('(pymysql.err.OperationalError) (3144, "Cannot create a JSON value from a string with CHARACTER SET \'binary\'.")')
'INSERT INTO platform_configurations (platform_name, configuration, id) VALUES (%s, %s, %s)'
('string', b'{"additionalProp1":"string","additionalProp2":"string","additionalProp3":"string"}', '01HEN04BMEKFV1SH55084F9JWX')
