character set warning in logs

I am using PXC 5.6 (Percona-XtraDB-Cluster-56-5.6.41-28.28.1.el7.x86_64) and my log file is flooded with this warning:

[Warning] Client failed to provide its character set. ‘latin1’ will be used as client character set.

how can I disable this warning?

Hello jazikh it looks as though this is related to a MySQL bug, here is one discussion

Here is the bug report:

A poster on StackOverflow reported that after updating the connector the issue was resolved, might this apply here?

Are you using HAProxy as well? You may find this report interesting:

Actually, no. We are not using haproxy. Only using keepalived. We have 3 nodes cluster and using single node for read and write.
