If you use the Window Title applet, found at gnome-look.org ( http://gnome-look.org/content/show.php?content=103732 ) with XfApplet, the title is cut off at what seems to be a certain pixel width; it cuts off/through whatever character hits that spot, rather than simply omitting it.. so I don't think it's about character spacing.
Everything else seems to work fine. I have an example screenshot in this thread:
