OK, this also works for me.
Which implies the pdffonts use CN-GB encoding for Chinese font name 
as you mentioned.
My guess on last post is: when poppler tries to find font through 
fontconfig, will they handle CN-GB encoding font name well? Does 
fontconfig also support CN-GB encoding for Chinese font name? 
If fontconfig doesn't support CN-GB encoding, it will report no such
font to poppler! 
How can I find whether font name encoding not being utf8 cause my 
problem or not?

As I said I already have them, according to fc-list.

These two output nothing, I don't have them.

I can't get usable fonts by just setting LANG env variable. But that's
another problem, because the pdf file doesn't use the last two fonts
according to both acrobat and pdffonts tool.

Please tell me if there is other ways I can get more debug output or log.
