Fix Adobe Acrobat Typing Symbols Instead of Normal Text
Question details
The user needs to resolve an issue where typing into a PDF form or comment box produces symbols or gibberish characters instead of regular text.
- Product
- Adobe Acrobat Reader
- Device & OS
- not provided
- Scenario
- Filling out a PDF form or adding text comments using annotation or Fill & Sign tools.
- Observed behavior
- The PDF reader inserts incorrect symbols instead of the actual alphabetical characters typed on the keyboard.
Verify that your system keyboard layout is set to the correct language and ensure you are editing the file directly in a dedicated PDF application rather than a web browser.
Change the Font in the PDF Text Field or Comment Properties
Switching the input font to a standard system font can bypass character encoding errors caused by missing or corrupted embedded fonts.
Often, PDF creators embed customized fonts. If your system cannot map these fonts correctly, Adobe Acrobat replaces your keystrokes with symbols. Overriding the font property for the specific text box usually resolves this instantly.
Click on the form field, Fill & Sign text box, or comment where the gibberish symbols are appearing.
Press Ctrl+E on Windows or Cmd+E on Mac to display the Text Properties toolbar.
Highlight the symbols you typed and change the font drop-down to a widely supported standard font, such as Arial, Helvetica, or Times New Roman.
Update or Repair Adobe Acrobat Installation
Updating or repairing the software can fix underlying bugs or missing resource files that cause text rendering failures.

Frequently Asked Questions
Why does my PDF show symbols instead of text when I type?
This happens due to font substitution errors or corrupted embedded fonts in the PDF file. If the PDF reader fails to map your keyboard inputs to the embedded font's character set, it displays placeholder symbols instead of actual letters.
Can I fix the symbol typing issue without buying Adobe Acrobat Pro?
Yes. In the free version of Adobe Reader, you can often highlight the problematic text and use the Properties toolbar (Ctrl+E) to switch the font to a standard option like Arial. Alternatively, opening the document in a different free PDF editor like WPS PDF can bypass the issue.
Does copying and pasting text fix the symbol issue in PDFs?
Sometimes pasting text from a plain text editor like Notepad can bypass the font glitch. However, if the PDF form field is strictly hardcoded with a corrupted font, the pasted text may still convert into symbols until you change the font properties.
How do I know if the PDF file itself is corrupted?
Try opening the PDF file in a web browser like Chrome or Edge. If you can type text normally into the form fields within the browser, the file is fine. The issue is likely specific to your PDF reader's font settings or installation.
