[Encountered Issue: Phenomenon and Impact] When using sync-diff-inspector to verify MySQL 8.0.33 data, it cannot recognize the utf8mb3 encoding format.


Where can I modify the encoding format?

May I ask which version of TiDB you are using? According to the documentation, it seems that utf8mb3 is only supported in TiDB 7.2. I’m not sure if this diff tool is supported, as I haven’t seen any documentation on it.

Isn’t it utf8mb4?

You can replace mb3 with mb4 in the database, right?
