Sincerely neighborhoods , built on Mina server transport garbled

We did a project to do with mina server for socket communication , and found that when communicating with the Chinese , in the decoding process will produce garbage problem .
This is the process of decoding the code

  public void decode(IoSession session, IoBuffer in, ProtocolDecoderOutput out)throws Exception
  {
  	ByteBuffer buf = in.buf();
  	byte[] msg = new byte[buf.limit()];
  	buf.get(msg);
            String ss = new String(msg,"UTF-8");
            out.write(ss);
            out.flush();
