Description:
The special chars (ex: !!! or ???) present on the end of the line, it's position is changed from the actual position when you set the component orientation to R to L.

For Example, take the following string
"Swing is cool!!!" when the orientation is set to right to left this string should placed at the extreme right and special chars position should not be changed. But the actual behaviour is "!!! Swing is cool".

Steps to reproduce this problem:
1. Launch the sample application
2. Now check the check box "rtl, for the component orientation take effect press a key at the end of a line.

Now you can see the string got placed at the extreme right and special chars position got changed.

The sample code to reproduce this problem is

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