How to generate Chinese characters from a Java servlet?

My servlet looks like this 

  protected void processRequest(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException
  {
    PrintWriter out=response.getWriter();

    out.println("<Html><Head><Title>Signup</Title></Head>\n<Body>\n");
    out.println("\u5982 电话\n");
    out.println("</Body>\n</Html>");
  }

My browser can display Chinese characters from other websites. I'm trying 2 different ways to display Chinese characters, but they all showed up as ??? What's the correct way to do it ?

Just setting the character encoding as UTF-8 worked for me. 

response.setCharacterEncoding("UTF-8")

You would need to send Unicode, have your servlet send UTF-8, and have the browser locale set up properly to interpret the characters correctly.

No explicit encoding has been set for the response. The response would therefore be written by the container with the default encoding of ISO-8859-1.

You'll therefore need to specify the appropriate character encoding using the HttpServletResponse.setCharacterEncoding() or HttpServletResponse.setContentType methods. This would be either of:

response.setCharacterEncoding("GB18030");
response.setContentType("text/html; charset=GB18030");

You may also use UTF-8 as the explicit encoding.

Try adding

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
