- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Typing text or numbers into fillable fields within a PDF form.
- Observed behavior
- Text and numbers display as question marks inside squares when entered in Adobe Acrobat, even though the file functions properly in other PDF viewers.
Before proceeding, check if you have the necessary permissions to edit the PDF form and ensure that your Adobe Acrobat is updated to the latest version to rule out software bugs.
Change the PDF Form Field Font Settings
Modifying the font property of the specific form field to a standard, universally supported system font can resolve character rendering issues.
This issue typically arises when the PDF creator assigns a specific font to a form field, but that font is either not embedded in the document or not installed on your device. Adobe Acrobat struggles to substitute it, resulting in missing characters or question marks.
Launch Adobe Acrobat, open the problematic PDF document, and select 'Prepare Form' from the right-hand tool pane.
Right-click on the specific form field where the question marks appear and select 'Properties' from the context menu.
Navigate to the 'Appearance' tab in the Properties dialog box. Click on the 'Font' dropdown menu and select a standard, widely supported font such as Arial, Helvetica, or Times New Roman.
Click 'Close' to apply the changes, then try typing in the form field again to verify that the text renders correctly.
Request File Modification and Re-Embedding
If the PDF is secured or you lack editing tools, the form creator must embed the fonts properly.

Frequently Asked Questions
Why does my typed text turn into boxes with question marks in PDFs?
This happens when the font designated for the form field isn't embedded in the PDF and isn't installed on your computer. Adobe Acrobat fails to find a suitable substitute, displaying question marks instead of characters.
How can I tell if a font is embedded in a PDF document?
In Adobe Acrobat, go to File > Properties, and select the Fonts tab. This will display a list of all fonts used in the document. If a font says '(Embedded)' or '(Embedded Subset)' next to its name, it is correctly stored within the PDF.
Can I fill out an interactive PDF form without Adobe Acrobat?
Yes. If Acrobat is giving you rendering errors, you can use highly compatible alternative software like WPS Office to fill out your PDF forms smoothly without dealing with complex font configuration issues.
