- Scenario
- Copying text from a PDF using text editing tools and pasting it into another application.
- Observed behavior
- Certain characters disappear from the copied string when pasted into the destination software, often triggered by using the Edit Original Document Text tool instead of a standard selection tool.
Before proceeding, check if your PDF is a scanned document or uses heavily customized fonts, as these often require specialized OCR processing to extract text correctly.
Use the Standard Text Selection Tool
Switching from the 'Edit Text' tool to the standard 'Text Selection' tool ensures that the clipboard captures the underlying text accurately without attempting to edit the source formatting.
The Edit Original Document Text tool is specifically designed for modifying the PDF's internal content blocks. Using it to copy large portions of text can lead to encoding errors or dropped characters.
By utilizing the standard Text Selection tool, your PDF viewer reads the embedded text layer directly, minimizing the risk of missing characters when transferring to another app.
Locate and click on the 'Text Selection' tool in your PDF reader's main toolbar, typically represented by an arrow or an I-beam cursor icon.
Click and drag your cursor over the text you wish to extract to highlight it.
Press Ctrl+C (Windows) or Cmd+C (Mac) on your keyboard, or right-click the highlighted area and select 'Copy'.
Open your target application, click where you want the text to appear, and press Ctrl+V (Windows) or Cmd+V (Mac) to paste the text.

Frequently Asked Questions
Why does text copied from a PDF sometimes look like gibberish or contain blank spaces?
This happens when the PDF creator embeds a custom font without a proper Unicode mapping table. The system can display the visual shape of the letter but doesn't know what underlying character it represents, resulting in gibberish or blanks when copied.
How can I copy text from a scanned PDF that won't let me highlight anything?
A scanned PDF is essentially an image of text. To copy from it, you must first use an OCR (Optical Character Recognition) tool to scan the image and convert it into selectable text blocks.
Can pasting without formatting fix the issue of missing PDF characters?
Sometimes. If the missing characters are caused by the destination application attempting to render a font it does not have, using 'Paste as Plain Text' (Ctrl+Shift+V) strips the formatting and forces the software to display the raw characters using a default font.
