  public static final String EURO = "\u20ac";

  public void init () {
   setLayout(new FlowLayout());
   Label a = new Label(COPYRIGHT + " R\u00e9al Gagnon");
   Label b = new Label(REGISTERED + " R\u00e9al's Software "
                       + " price : 100 " + EURO);

The Indian rupee symbol ( ₹ HTML entity : ₹) is quite new (2010) so you need to make sure that the Font that you are using has it. To display it from Java, you need to use Swing because AWT won't be able to display it. 

import java.awt.*;
import javax.swing.*;

public class TestUnicode extends JApplet {
  public static final String RUPEE = "\u20B9";

  public void init () {
   setLayout(new FlowLayout());

   JLabel b = new JLabel("rupee : " + RUPEE);
   b.setFont(new Font("Arial", Font.PLAIN, 14));
   add(b);
  }
}
