Question details
The user needs to prevent spaces and line breaks from vanishing when entering text into a PDF text box.

- Product
- Adobe Acrobat XI Pro
- Device & OS
- not provided
- Scenario
- Typing text with spaces or line breaks inside a PDF text field or text box.
- Observed behavior
- Spaces and line breaks disappear immediately after the user clicks outside the text box.
Verify if the PDF document contains any restricted or unembedded fonts, as modifying text with unsupported font encodings often triggers spacing issues.
Troubleshoot Missing Fonts and Use the Edit Text Tool
Check for font warnings and ensure you are using the correct content editing tool to maintain proper text formatting.
Text spacing issues in older PDF editors frequently occur due to font mapping errors or because the document uses a font not installed on your local machine.
Open the PDF document and look for any missing-font warnings at the top of the screen or within the document properties.
Select the text in your text box and change the font to a standard, widely available system font (such as Arial or Times New Roman) to see if the spaces are retained.
Navigate to the Tools pane on the right side, select 'Content Editing', and click on 'Edit Text and Images'.
Click inside the text box using this specific tool, re-enter your spaces and line breaks, and click outside to confirm they remain visible.

Frequently Asked Questions
Why do spaces disappear in PDF text boxes?
This usually happens due to missing embedded fonts in the PDF or limitations within older software versions, like Acrobat XI, improperly handling specific text encodings when saving text box content.
Can I fix missing fonts in a PDF without the original file?
Yes. You can select the affected text and change it to a standard system font that your computer currently has installed, though this may slightly alter the document's original appearance.
Is Adobe Acrobat XI Pro still supported?
No, Adobe officially ended support for Acrobat XI in October 2017. It no longer receives bug fixes or security updates, making it prone to glitches. Upgrading to modern alternatives like WPS Office is highly recommended.
