    Description

      After updating to 2.6.1, our services started to throw the following exception when trying to connect to mysql. 

      Could not connect to HostAddress{host='example.com'', port=1234, type='master'}. (conn=595723) Variable 'character_set_client' can't be set to the value of 'utf32'

      We don't set `character_set_client` explicitly, and all of our tables are set to utf8mb4. We set `charset` to `utf8mb4` on the connection string to Mysql.

      Reverting back to 2.6.0 fixes the issue.

            I see exactly the same problem, with the same resolution. I can't find anywhere that we are explicitly setting character_set_client.

            this is a regression introduced by CONJ-797.
