Subject: [PATCH] Create tables with a charset that can hold all expected data
under mysql (#43732)
By default these tables are created with utf8 which can only hold 3 bytes. This
meant that all emjoi would trigger a MySQLdb._exceptions.OperationalError because
they are 4 bytes.
This will only fix the issue for users who recreate their tables.
