When using adobe acrobat pro dc to edit the text of a PDF file, it shows that there is no available font "Microsoft Ya Hei Ui Light", which is automatically replaced by another font, but the original text is Microsoft Ya Hei font, in order to maintain consistency need solve this problem.
The reason for the analysis is that this font is missing in the system, so just download it from the Internet and add it to the system. After some twists and turns, I found the font I wanted, moved it to the /Library/Fonts directory after downloading, and restarted Adobe Acrobat Open the PDF again to use the font, and the lack of other fonts is the same.
Or you can use the Font Book app to add (File -> Add Font to "Current User" -> Select the downloaded font file).
