The issue looks similar to this one:

I am on 3.3 server sorry for the mistake. The version I am using is 3.3

And UTF-8 is already set in wrapper and all said in the above post is done still this error is returned.

Does this error affect, performance of server instance or any other functionality? Can I safely ignore it for now?

Those issues don't affect the performance, but it means you are losing some data as it can't be saved in the database.
