Incorrect string value: '\\xF0\\x9F\\x91\\x8F\\xF0\\x9F...'
After updating from MySQL Connector/J 5.1.47 to 8.0.13, my service is sporadically getting into a state where any attempts of inserting Unicode values gives errors along the lines of:
Incorrect string value: '\\xF0\\x9F\\x91\\x8F\\xF0\\x9F...'
My database, table and columns are all set to utf8mb4. Historically I have not included any character encoding options in the URL, but I have tried including characterEncoding=UTF-8 and it did not help. My server is currently running with the following settings:
character_set_client: utf8mb4
character_set_database: utf8mb4
character_set_results: utf8mb4
character_set_connection: utf8mb4
collation_connection: utf8mb4_bin
collation_server: utf8mb4_bin
character_set_server: utf8mb4
I never had any issues on Connector/J 5.1.47. The trouble started after upgrading to 8.0.13. Is this a known problem? How can I further debug it?
