how to display unicode characters(e.g. chinese,japanese) in java application?

I have tried below code, but only '?' gets printed instead of unicode characters.

public static void main(String s[]){

  char i2 = 0x0AFF;
  String str = "A\u0303";
  System.out.println(str);
  System.out.println(i1);
  System.out.println(i2);
}

I am using jdk1.6. Thanks for any help in advance.

This probably has more to do with the OS you are on. Java handles unicode internally, no problem but once it's written to the stdout, it's up to the console/pipe receiving it to be able to understand and print it on the screen or in the file. Windows console does not support printing unicode characters.
