Non-English characters

Question

Hello, I have read several times that since Java uses Unicode, it solves the problems of non-English characters automatically or something like that.
But my app is not working as expected. Would someone help please?
I have a client/server combo written in Java. The server can send messages in English or Japanese. The Japanese messages are hard-coded as String literals in the server source code. On the client side, they are displayed on a JEditorPane. But the Japanese characters are all garbled. The OS on the server side and client side are, of course, different.
My supposition, which is obviously wrong as it is not working, is that since both ends of communication are Java app, I need not worry about any encoding conversions for String literals.
Suggest me what is wrong here?

Answer 1

How is the required encoding/decoding supposed to be done?
When I didn't worry about non-English characters, I did the following, which WORKED.
// SENDER side
Socket socket ;
PrintWriter     out = new PrintWriter(socket.getOutputStream(),true);
String outMessage = "my message";
out.println(outMessage);//RECEIVER
Socket socket ;
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String inMessage =  in.readLine();When non-English characters are involved, I did the following, which DID NOT WORK. Please someone correct me.
// SENDER side
Socket socket ;
PrintWriter     out = new PrintWriter(socket.getOutputStream(),true);
String outMessage = "my message";
String utfString = new String(outMessage.getBytes(),"UTF-8");
out.println(utfString);//RECEIVER
Socket socket ;
InputStreamReader ins = new InputStreamReader(clientSocket.getInputStream(),"UTF-8");
BufferedReader in = new BufferedReader(ins);
String inMessage =  in.readLine();The received message is still garbled.
