Hi Betoman,
Can you confirm if you have already installed the Chinese language pack in your computer? You need to have this to ensure that your computer will recognize and display the characters correctly (this will also fix your Little Math display problem).
For instructions on how to install language packs for your computer, please have a look at this article:

I hope this helps!
