Description Tasuku Suzuki 2011-02-28 00:51:13 PST 
How to reproduce:
* build and run the example attached
* wait until http://google.co.jp/ is loaded
* make sure you see Japanese Version of the site
* click the button on top (PushButton)
* print preview appears
* check the button "Google 検索" and text "Google について" are not printed correctly

Notes:
* I reproduced this issue with Qt 4.7.1(MinGW) bundled with Qt SDK 1.1 TP on Windows 7 and Mac OS X(10.6)
* Neither print preview nor printing to a printer looks fine.
* It seems to happen only for text that contains both latin and non latin characters.

I wonder if this is a regression.
Jocelyn, do you think this can be linked with fast font path?

Looks like reported text's width isn't the same as the drawn one. We had similar regressions with the fast font path since the metric code paths are a bit different when measuring and drawing, so this might be linked yes.

Chinese pages have the same problem.

But I found it can be solved by set the font-family to the chinese fonts in the CSS.

So...How about Google now...

And it seems that the problem appeared after Qt4.7, Qt4.6.3 works fine.
