Question
PDF font changed automatically with my new computer
It confused me for a while when I upgrade my PDF reader to Acrobat Reader DC (now it's version 2017.009.20044).
Some of my previous PDF files (converted from PowerPoint or Word) show font changed (as below).

I've tried several ways, such as checked and uncheck the box "using local font", change "never" use PDF/A mode...etc. but didn't work.
But the document shows normally when I try to use 3rd party software such as "Foxit reader".

How can I fix it with my Acrobat Reader?
