ReadLine中的Android问号

Question

您正在构建一个使用tcp的消息传递应用程序，每当我发送带有希伯来语字符的字符串时我都会得到问号，并且我已经尝试使用新的字符串转换字符串（serverMessage.getBytes（），＆＃34; UTF- 8＆＃34）; 但它没有在这里工作是我的代码：

   try {
            //send the message to the server
            out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
            //receive the message that the server sends back
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));

            HelloService.firstTouch();


            //in this while the client listens for the messages sent by the server
            while (mRun) {
                serverMessage = in.readLine();
                String temmmd = new String(serverMessage.getBytes("UTF-8"),"UTF-8");

                if (serverMessage != null && mMessageListener != null) {
                    //call the method messageReceived from MyActivity class to inform main activity that a message has received
                    mMessageListener.messageReceived(temmmd);
                }
                serverMessage = null;
            }

        } catch (Exception e) {

        } finally {

            socket.close();
        }

    } catch (Exception e) {

    }
