MS Office renders math symbols wrong on non-English system

[nixlayzzer]

I am using Linux x86_64 (tested on different distros). I have Microsoft Office 2007 or 2010.
Equations by "insert -> object -> Microsoft Equation 3.0" or Mathtype render some math symbols (like integration , sum ) as "?".

My system and Office language is simplified Chinese (zh_CN.utf8).

English environment doesn't have that problem.
If use

Code: Select all

env LC_ALL=en_US.utf8 wine ......

to run Word, symbols can be displayed correctly.
