some of my friends and I can't render traditional Chinese characters out but some of my friends can. Not sure if this is related to the font setting on OS.
Not sure why some macs can render chinese properly but some can't.  Anyway, I check how pdfium gets using of fonts and it seems that pdfium uses embedded fonts.[1]

I'm closing this bug as WONTFIX per:

"The Mortar experiment has concluded. Mozilla does not consider the PDF use case justifies the burden of implementing and maintaining PDFium and a Pepper API implementation in Gecko."
