Even in the newest versions there still is a problem with special characters.
As you can see in the appended example the right side shows "Très vite et très gai" in the correct way while the title tag on the left shows track four with brocken characters "Tre s vite et tre s gai".
That happens every time if you copy a phrase in Safari (strangely not with Google Chrome) and paste it into the title tag.
