That wouldn't explain though why it works on Mac and Linux, no?

There are two code paths in WebKit, a fast text code path and one for complex 
text (note how it's not called slow ;). I'm not 100% sure, but I think the 
chinese characters would likely go through the fast text code path, which is 
indeed using QRawFont. If that is the case, then it may be a matter of not 
finding the right fonts on Windows.
