Social.localUser.userName returns some word in Japanese

My username in google player is “Sahkan Sahkan”.
After authenticating I’m getting something like 浯牥汥慦獳a in the log.
(“Welcome 浯牥汥慦獳a”);

I have the GooglePlayUnityPlugin installed and it is all working good besides the fact that I get Japanese words in the userName and id.

This is the code I use to authenticate:

Social.localUser.Authenticate((bool success) =>
        {
            if (success)
            {
                Debug.Log("Social.localUser.Authenticate Welcome " + Social.localUser.userName);
            }
            else
            {
                Debug.LogError("Social.localUser.Authenticate Authentication failed.");
            }
        });

Anyone?..

Did you manage to find out why? I have the same issue.
