Dynamically changing font - Ugly chars on Win 2000

Question

Hi,
I wrote simple class called FontChooser (extends JDialog). It can be "plugged" into any JFrame to change font at runtime. Looks like ordinary font dialog, nothing special.
The FontChooser itself works (IMHO) just fine but I'm facing a problem: Almost all PLAIN fonts on Windows 2000 (sp4) have several ugly characters. For example Tahoma PLAIN 11 has ugly char '8'.
Strange is that BOLD fonts are always displayed OK - the ugly things are "covered".
The only font that's OK is Arial. (Any size, any style.) Brobably because it's the Swing default font.
Changing the font is done by this method:
* The method simply iterates through the table of  GUI keys and updates every key whose name ends with "font".
Thus, FontChooser is not able to deal with different fonts at the same time.
public void updateFontKeys(FontUIResource font) {
  UIDefaults def = UIManager.getDefaults();
  Enumeration en = def.keys();
  while(en.hasMoreElements()) {
    String key = en.nextElement().toString();
    if(key.toLowerCase().endsWith("font"))
      UIManager.put(key,font);
// Note: FontUIResource is just a new (Swing)
// "version" of java.awt.Font.I also tried to change Swing component's font using html
- instead of changing gui keys - but the result was the
same :o(
Any hint will be very appreciated :o) Thanks.

You can download FontChooser (with a simple demo app) from http://www.volny.cz/dojcland/gui/FontChoosing.zip
The archive includes binaries, source and javadoc.
