an example of document with equation

I installed Microsoft Office Professional Plus 2010 in a clean 32-bit
wineprefix.
After copying fontsub.dll and t2embed.dll from Windows XP and setting them to
native, build in override, I can embed Fonts when exporting to PDF. However,
When a font is in a TrueType fonts collection(*.ttc), it cannot be embed and
become bitmaps in PDF, such as SimSun fonts. Moreover, when I enter a math
equation in Word. I can't see the equations in the exported PDF.
The font of the equation is Cambria Math. So I tried to substitute the TTC font
CAMBRIA.TTC with Cambria.ttf and CambriaMath.ttf which was unpacked from it,
and try it again. After that, the interface of Microsoft Word become quite
strange and it cannot work normally.
So what I want to know is whether there is a way to export PDF with TTC fonts
in Microsoft Word 2010 with wine.
