Font display issue

[JeanPierrePapin]

Good morning,

I have an issue on a single computer (it works fine in the other one) displaying some pdf with Acrobat reader as you can see in screenshot. If I open the file in a browser I can see font properly. Any idea?

Thanks

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.

Thanks for your answer. I confirm release is the latest 24.003.20180. Issue occurs only with some pdf not  only with one. If I open the same pdf in another pc it visualizes font correctly so it is not a file issue.
About preferences, I haven't Use local font option as you can see in attached screenshot.

Hello @NicoleColovos

I hope you are doing well, and thank you for reaching out.

I am sorry for the trouble. The issue has been addressed. Please ensure you have the latest version of Acrobat, or the freeware Acrobat Reader, installed on the machine: 25.001.20997. Planned update: December 9, 2025. Check for any pending updates by navigating to Menu > Help> Check for Updates. Install the updates, restart the app and the machine, and try again.

For testing purposes: 

• Open Acrobat Reader

• Go to Menu > Preferences > Security (Enhanced)

• Temporarily uncheck Enable Protected Mode at startup

• Restart Reader and test the file.

If the PDF uses Asian/CID fonts (Identity‑H), ensure Asian font packs are installed or enabled in Reader. Without them, the Reader substitutes or shows boxes, while browsers use system fallback.

Open Menu Properties > Fonts on the affected machine and compare with the good machine. If you see AdobeSerifMM/AdobeSansMM or “(substituted)” on only one PC, it’s a local font/pack issue.

Let us know how it goes.

Thanks,

Anand Sri.
