loadrunner11 The Chinese log of server in Replay Log show the mess

I use Loadrunner to write a HTTP request script in the Java Vuser.Then I use web.reg_save_param() to receive the response.But the response log in Replay Log show the mess.I have no idea to resolve it.The logs are following:

`Notify: Saving Parameter "resp = HTTP/1.1 200 OK\r\nServer: Apache- 
Coyote/x.xx\r\nContent-Type: text/html;charset=UTF-8\r\nTransfer-Encoding:
