Question details
Users need to resolve an issue where Acrobat and Adobe Reader report that an embedded font cannot be extracted, resulting in garbled text.
- Product
- Adobe Acrobat and Adobe Reader
- Device & OS
- Windows and macOS
- Scenario
- Opening or printing a PDF document containing embedded custom fonts after a recent Adobe application update.

Ensure you have a backup of the original PDF document and check its properties to identify the exact name of the problematic font before proceeding.
Report the Font-Embedding Bug to Adobe Support
Since this error is primarily caused by an Adobe application update bug affecting font extraction, providing specific details to Adobe helps them investigate and release a software patch.
This issue frequently affects business fonts (like DIN Regular) after installing a new Acrobat or Reader update. Documenting the environment and sharing a sample file is the officially recommended approach for a permanent fix.
Write down your exact operating system version (Windows or macOS) and the current version of Adobe Acrobat or Reader installed on your device.
Determine how the PDF was originally created, including the source application (e.g., Microsoft Word, Adobe InDesign) and the export settings used.
Contact Adobe Support or visit the official bug reporting forum to provide them with a sample PDF file and the details you gathered for investigation.
Re-export the Original Document
If you urgently need a working PDF and have access to the source file, re-exporting the document with modified font settings can bypass the reading error.
Open and Print PDFs flawlessly using WPS PDF
If Adobe Acrobat is unable to extract embedded fonts due to a software update bug, you can bypass the issue entirely by using WPS PDF. WPS Office uses an independent rendering engine that smoothly opens, reads, and prints your documents without encountering the 'bad or missing data' error.
- 1. Download WPS Office: Download and install the free WPS Office suite on your Windows or Mac computer.
- 2. Launch WPS PDF: Open the WPS Office application and click on 'PDF' from the main dashboard.
- 3. Open the problematic file: Click 'Open File' and select the PDF document that was returning the font error in Adobe Acrobat.
- 4. View and print normally: Read, edit, or print your PDF document seamlessly without missing character data.

Yes, this specific font-embedding extraction failure has been reported to affect users on both Windows and macOS operating systems running updated versions of Adobe Acrobat or Reader.
How can I check which fonts are embedded in my PDF?
You can verify embedded fonts by opening your PDF in a reader, navigating to 'File' > 'Properties', and clicking on the 'Fonts' tab to see a list of all fonts used and their embedding status.
Can I fix this error without waiting for an Adobe update?
