Question details
Users experience corrupted characters, such as question marks inside rectangles, when pasting text into a PDF form field.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Pasting clipboard text (both plain and formatted) into an interactive PDF form field.
- Observed behavior
- Pasted text displays as question marks inside rectangles due to a formatting conflict, whereas manually typed text displays correctly.
Ensure that your PDF software is up to date, as this specific rich text formatting issue is a known bug in older versions like Adobe Acrobat X.
Disable the Rich Text Format Setting for the Form Field
Turning off rich text formatting prevents formatting conflicts that cause characters to corrupt during the paste action.
This is the most direct solution if you have permission to edit the form field properties. The issue is often caused by how the PDF editor interprets the clipboard's rich text data.
Open the PDF document in Acrobat and select the 'Prepare Form' tool from the right-hand pane to enter editing mode.
Right-click the problematic text form field and select 'Properties' from the context menu.
Click on the 'Options' tab located at the top of the Properties dialog box.
Find the 'Allow Rich Text Formatting' checkbox and uncheck it.
Close the Properties window, exit form editing mode, and attempt to paste your text into the field again.
Use a Temporary Plain-Text Field as a Workaround
If you must retain rich text functionality in your final field, you can sanitize the clipboard content using an intermediate plain-text field.

Frequently Asked Questions
Why do pasted characters turn into boxes or question marks in PDFs?
This usually happens when there is a font encoding issue or when rich-text formatting from your clipboard conflicts with the form field's internal settings.
Does this issue affect all versions of Adobe Acrobat?
While it is a well-known bug specifically reported in Acrobat X, similar font or clipboard formatting conflicts can occasionally occur in other versions as well.
Can I fix the corrupted text without changing field properties?
Yes. You can try pasting the text into a plain text editor like Notepad first, copying it again, and then pasting it into the PDF form. This strips away any hidden formatting.
How do I enable or disable rich text in a PDF form?
In your PDF editor's form preparation mode, right-click the text field, select Properties, go to the Options tab, and check or uncheck the 'Allow Rich Text Formatting' option.
