Font display issue

Hi JeanPierrePapin!

I hope you're doing well. Thanks for reaching out.

We're sorry to hear about your trouble with the Acrobat Reader app. Could you please let us know the version of the app you have installed? You can find this by going to the Help menu, selecting About Acrobat Reader, and then sharing the version number with us.

Is the issue occurring with all PDFs or just a specific type? If it's specific to one PDF, try with other PDFs.

Please ensure you have the latest version of the app installed, which is 24.003.20180. Check for any pending updates from the Help menu by selecting Check for Updates, then install them and restart the app and your machine.

Please follow these steps:
File(Win), Adobe Acrobat (Mac) > Preferences > Page Display; under rendering, select 'Use Local Font' > Click OK. Restart the app, open a PDF, and check.

Please ensure that the PDF file is created correctly and that all accessed fonts are adequately embedded within the PDF file. If you are the owner of the PDF file, try creating it again using the Acrobat app. 

Refer to this article for more suggestions, and let us know how it goes: https://adobe.ly/3XRJs0d.

Thanks,
Anand Sri.
