Welcome to the Ranch
128…255 are not ASCII characters. I suggest you read about the history of character encoding here.
Java can display any Unicode character, but not every platform can. The Windows® command line is notorious for its inability to display characters. Rather than using System.out.println, try a Java applicatoin, eg JOptionPane.showMessageDialog(null, "™ˆª");

Hi,

Basically, The characters (with ASCII>=128)that you want to display, will display to an outputstream that has been encoded properly.

Unfortunately in this case the PrintStream is not encoded with the necessary encoding.
You can try encoding your PrintStream.
Or,you can try outputing the characters to a File (FileStream) and encode it with UTF-8.

You can also check out this sample program

import java.io.PrintStream;

public class EncodePrint {
   public static void main(String[] a) {
      try {
         PrintStream out = new PrintStream(System.out,true, "UTF-8");
         System.setOut(out);
         for(char c = 128;c<256;c++)
              System.out.println("Got char = " + c);
      } catch (Exception e) {
          e.printStackTrace();
      }
   }
}

I have already given you one way to do it.

[Gihan Pandigamage]

try this

for (int i = 0;i < 256;i++){
byte[] b = new byte[] { (byte)Integer.parseInt(i) };  
String s = new String(b, "windows-1252");  

System.out.println(s);
}

No it ISN'T. I suggest you read Campbell's link before making statements like that.
