Normally, installing Chinese language to your installed language list in Control Panel\Clock, Language, and Region\Language should work.
But it seems you still have troubles viewing Chinese characters.
Try changing your system locale to Chinese. Go to Control Panel\Clock, Language, and Region and click Region.
In Administrative tab, click Change system Locale... and select Chinese. click OK all your way out to close the dialog boxes. Reboot.
Thanks for your thoughts. Oddly enough, it seems to have worked itself out overnight.
I ran into this problem today...
So turns out that the language pack helped… but wasn’t the solution. Once the language pack was installed and set to "system Locale" it would display correctly on the screen … everything appeared correct. However, once you try to save a PDF, the file would error out with the following. (Arial Unicode MS error). If you continue to make the PDF, the text that is supposed to be Chinese characters is now completely missing when the PDF file is viewed.
Turns out, you have to have a specific Microsoft font installed. I installed MS Word and Excel (2013) and it now works like other computers. I also uninstalled the language pack and it still works the same.
Lastly, the Solidworks KB has this issue listed, however it does not list this fix.
I was installing SW 2012 sp5 on a Win 2008 r2 VMware server to be a PDM host for EPDM.
