Description:  
Error log gets filled with spam like this: [Warning] Client failed to provide its character set. ‘latin1’ will be used as client character set.  
[Warning] Client failed to provide its character set. ‘latin1’ will be used as client character set.  
How to repeat:

- HAProxy’s mysql-check option causes this warning as well. A solution for suppressing this warning would be helpful to keep error logs clean.
- Simplest example, login to server with an 4.0.forever client.  
I tried to disable the warnings from my.cnf using log-warnings=0 and log\_warnings\_suppress=1592 but without any result, warnings are still there.  
Distro: Ubuntu Precise (12.04.4)  
Error log:
- Size: -rw-r----- 1 mysql root 1.1G Jun 12 16:45 staging.err
- Message: 2014-06-12 16:45:41 1243 [Warning] Client failed to provide its character set. ‘latin1’ will be used as client character set.
