Bug 25458 [Font] DBCS support: new SWT API
Last Friday we have included a new API in Font: public Font(Device device, FontData[] fds) { In order to have a more appropriate behavior on DBCS platforms Eclipse/UI should start using this API. Anyway, the best police still is never change the default font in the widget if you don't need to. (this new API is going to make difference in Eclipse/Motif only)
bundles/org.eclipse.jface/src/org/eclipse/jface/resource/FontRegistry.java
return defaultFont();
	
	return font;
}
/**
 * Shut downs this resource registry and disposes of all registered fonts.
 */
private void handleDisplayDispose() {
	for (Iterator e = stringToFont.values().iterator(); e.hasNext();) {
		Object next = e.next();
		if (next instanceof Font) {
			((Font) next).dispose();
		}
	}
	stringToFont.clear();
	listeners.clear();
}
/**
 * Hook a dispose listener on the SWT display.
 */
private void hookDisplayDispose(Display display) {
	display.disposeExec(new Runnable() {
		public void run() {
			handleDisplayDispose();
		}	
	});
}
/**
 * Checks whether the given font is in the list of fixed fonts.
 */
