Why does Acrobat Pro generate garbled copied-text PDF from Edge?

Greetings,

I've had this issue with Acrobat Pro and Microsoft Edge on Windows 10 (running on a Mac, via Boot Camp) for many years and on several computers (all Macs).

I'm running a completely clean installation of Windows 10, brand-new, recently formatted and installed using Boot Camp Assistant.  There's no way it has a corrupt font or anything.  (The only other software installed is Photoshop, Indesign, Illustrator, Autodesk AutoCad, Revit and 3ds Max, and OpenOffice.)

When I PDF from Microsoft Edge using Adobe Acrobat, the resulting PDF looks fine, but selecting text causes a huge selection highlight, and copy-pasting it leads to garbled characters.  See attached:

1. An article from a newspaper (it doesn't matter which web site it is, even my own webmail; they all cause the same problem).  

2. I PDF it using File - Print and Adobe Acrobat.

3. The resulting PDF looks fine.  But when I select any line, I get this huge blue highlight.

4. If I copy-paste that, the result is garbled text.

Acrobat works fine when PDFing from others applications.  Once again this is a problem I've had for years, on multiple computers.  I attach the garbled PDF.
