Update and Repair Adobe Acrobat Installation
Installing the latest updates and running the built-in repair tool can fix application-level glitches that cause incorrect text rendering.
Software bugs or corrupted installation files can interfere with how Acrobat processes keyboard inputs and renders fonts. Adobe frequently releases patches to address these text encoding errors.
Open Adobe Acrobat Pro DC, click on 'Help' in the top menu bar, and select 'Check for Updates'. If an update is found, follow the prompts to install it.
Close Adobe Acrobat completely and reopen it. Open your PDF and attempt to type the characters again.
If the problem remains, click on 'Help' again and select 'Repair Installation'. Wait for the process to complete, restart your computer, and test the PDF.
Verify and Fix Document Font Embedding
If the issue only happens in one specific document, the font may be improperly encoded or damaged, requiring a fix from the source file.

Frequently Asked Questions
Why does my PDF change letters to weird symbols when I type?
This typically occurs because the original font used to create the PDF is not installed on your computer, or the document uses a custom font encoding. When you try to type, the application cannot match your keystrokes to the correct character in that specific font, resulting in unrelated symbols.
Can I fix the incorrect characters by changing the font?
Yes. Selecting the affected text and changing the font to a standard, universally available system font (such as Arial, Calibri, or Times New Roman) can often resolve the symbol replacement issue immediately.
What does 'Repair Installation' do in Adobe Acrobat?
The 'Repair Installation' feature scans the software's core files for corruption, missing components, or registry errors and replaces them. This helps resolve unexpected software behaviors, including incorrect keyboard inputs and crashes.
How do I ensure fonts are correctly embedded when making a PDF?
When exporting a document to PDF from a word processor like Microsoft Word, check your 'Save As' or 'Export' options. Look for a setting or checkbox labeled 'Embed fonts in the file' to ensure all characters will display and edit correctly on any device.
