I actually asked the same earlier, as Chinese characters would randomly show and then not show. For example, I logged on today and at first they didn't show, then I rebooted and they did. I have no clue the rhyme or reason to it. I made a thread to ask here, figuring it was worth a shot, but not likely to produce any answers, which it didn't. But you can see the difference between them showing and not showing.

I have asked, and they do use some IME to type the Chinese characters, no clue which one though.
