Fonts show up as squares like they're missing but they're not.
I have a client who gets medical records mailed to them on CD's. When they open the file direct from the disk into Acrobat. Some fonts. From what I can tell it's Ariel, shows up and various size squares.
Now I can edit the page, change the font from Ariel, or another and back, then it will show up fine.
I can also open this pdf in a browser (chrome and Edge have been tested) and the font will show up just fine. I can also "print to pdf" from browser and open the file in Acrobat and the same thing happens. I have tested on multiple computers as well.
What is going on and how do I fix this?
