Chinese characters showing as question marks

This has been asked before, but I can't figure out what's wrong. I'm printing pdfs using phantomjs .render().

The rendered page is basically a local static site with these properties:

<meta charset="UTF-8">
font: normal 17px helvetica,arial,verdana,sans-serif
running and tested on Windows locally and Azure Worker Roles
Chinese language pack installed and working when printing the same page from Chrome (Installed fonts e.g. Arial Unicode MS, SimSun ...)

Latin characters are all fine, just Chinese ones are displayed as "?"

For example

I also tried the entire page in Arial or SimSun only, but no difference.

Any idea how to get this working on Windows?

Thanks!

You need a chinese font. None of them is in a chinese font family.

Result

Lastest to do, try to change your location to china. I don't expect this working, as I tried the phantomjs in win10 ENG preview, working very well. Control Panel > Region > Administrative > Language for non-Unicode programs
