Printing chinese character to system console in Java

Hi,

When I try to print a chinese character using
System.out.println("\u4e00");

it outputs a ? instead of the chinese character... what am I doing wrong? Thanks.
 
Are you sure that your console is capable of displaying Chinese characters?
 
Where are you viewing the output, the Windows command prompt? AFAIK 'cmd' doesn't support unicode, and by default it probably uses code page 437 (DOS ANSI?). Also, using System.out.println, from what I have experienced, is not particularly effective for non-ANSI strings, so if you want to output in Unicode explicitly (and not rely on any given system's default encoding), use a PrintStream object with System.out as your OutputStream, and specify the encoding.

Code: 
import java.io.PrintStream;
import java.io.UnsupportedEncodingException;

public class TestClass {

	public static void main(String [] args) throws UnsupportedEncodingException {
		String chineseString = "\u4e00\u4e01\u4e02\u4e03\u4304";
		PrintStream ps = new PrintStream(System.out, true, "UTF-8");
		ps.println(chineseString);
	}
}

In CMD, this will display something like this...

Code: 
一丁丂七䌄
or will be a bunch of ??? depending on your font.

In Eclipse editor, once I specify the console's encoding to UTF-8, I get this...

Code: 
一丁丂七

Click to expand...

I just changed the console encoding to UTF-8 in eclipse, but it's printing a bunch of squares... anything else I'm missing?

Edit: I think it's working now, it was \u4e04 instead of \u4304. Thanks everyone.
