Java Output UTF-8 to Real Characters?

Question

In Java, how can I output UTF-8 to real string?

     我们

     \u6211\u4eec

        String str = new String("\u6211\u4eec"); 
       System.out.println(str); // still ouput \u6211\u4eec, but I expect 我们 to be an output

-----
String tmp = request.getParameter("tag");
        System.out.println("request:"+tmp);
        System.out.println("character set :"+request.getCharacterEncoding());       
        String tmp1 = new String("\u6211\u4eec");       
        System.out.println("string equal:"+(tmp.equalsIgnoreCase(tmp1)));
        String tag = new String(tmp);       
        System.out.println(tag);

request:\u6211\u4eec
character set :UTF-8
string equal:false
\u6211\u4eec

From the output, the value from the request is the same as the string value of tmp1, but why does equalsIgnoreCase output false?

Java String are encoded in UTF-16. I do not see any problem in your code, I would believe the problem comes from your console and it doesn't show correctly the content of the String.

If you are using eclipse, change your console encoding here to UTF-8

Eclipse > Preferences > General > Workspace > Text file encoding

did you try to display just one of them? like

   String str = new String("\u6211"); 
   System.out.println(str);

I bet there is a problem in how you create that string.
