In addition, when a page contains mixture of traditional and simplified Chinese characters, two different fonts are used. For the example on the right, the simplified characters 维 and 历 are rendered in Ming font, while the traditional characters (or characters common to both systems) are rendered in sans-serif. Apple can probably get away with internationalization because their website says so.
Usability issue: Hotkey Ctrl-+, Ctrl--, and Ctrl-0 for enlarging or shrinking font size don't work. Pressing enter after clicking on a radio button doesn't submit the form. It crashed within 5 minutes I started using, and continue to crash later.
