Solution for garbled pdf software with poppler as the backend (okular, epdfview, evince ...)

Like many friends, I do not want to see the garbled characters of poppler.
Later, I saw the software dependency and realized that okular and so on are based on poppler as the backend.
Official poppler descriptions are as follows:

Suggested Fontconfig font substitutions
Poppler is using fontconfig to do the font searching on the system for fonts that are not embedded into the pdf files. this is a list of recommended font substitutions that distributions/users shoshould have in their fontconfig configuration
That is to say, the poppler reads the font from the fontconfig configuration file to replace the font in the pdf. Therefore, we only need to replace the font. Similar to openoffice, openoffice accepts fontconfig in addition to its own font substitution.
 
If you have installed a lot of windows fonts, you will not be garbled. If you haven't installed it, you have to replace the font. The previous official wiki provides an alternative. of course, the premise is that you have installed poppler-data. Otherwise, Chinese characters cannot be displayed.
 
The following is my configuration file.
 
Specify one or more fonts for all Chinese characters

This parameter is specified separately when the body is used.

Of course, I also changed my Chinese font to a beautiful English font.
 
Correction: kpdf is not based on poppler.
