I'm using the Java 2 Platform Standard Edition,
Version 1.5.0 (1.5.0_06);
I've written many Java applications, some of them CLI apps, most of them
using frames, also a few Applets of varying complexity; I've read David
Heller's "Ground-up Java", and also "Core Java Volume 1"; I've also gleaned
ideas from Java source code freely available on the net.

It's just this blessed £ (pound) sign I'm having difficulty with on the
command line interface. As a simple example,

import java.awt.*;
import java.text.*;
import java.util.*;

public class CurrencyTest3 { // see p59 Core Java Vol 1
static double x=100;
public static void main(String[] args) {
 NumberFormat formatter = NumberFormat.getCurrencyInstance(Locale.UK);
       System.out.println(formatter.format(x));
 System.out.println("£");
}
}

The output of this program? U guessed it:
<strange u symbol here>100.00
<strange u symbol here>
Does the (American) Java SDK/JRE not support English symbols?
