Hi Joe Healey,
Greetings. Thank you for posting the thread to our community.
I understand your concern, it seems when you use Jost font into your PowerPoint slide and the exported slide doesn’t show the Jost format correctly.
After my test that I’m using the latest version of PowerPoint 16.90, when you export the slide there are two options to choose, the first is called “Best for electronic distribution and accessibility (uses Microsoft online service)”, the other one is called “Best for printing”:
When you select the first option, the exported PDF will convert the Jost font into Calibri as Jost is the 3rd party font which doesn’t natively support for the Microsoft online service. When you select the second option, the Jost font will be correctly showed in the exported PDF file. Here is my test result as reference for you:
Select Best for electronic distribution and accessibility (uses Microsoft online service) option:
Select Best for printing option:
In that case, I suggest you can try to select the Best for printing option to check whether the issue persists or not.
If your scenario isn’t matched to my test result above, Please be free to contact and send feedback to me. I’m glad to help you further.
Hope you having a nice day.
Sincerely,
