I have a strange problem with one of my PDF files. In some places (usually where the text is bold), all the letters are invisible except for the "a"'s and "v"'s. When I copy the text and paste it into another program, I can see the letters displayed normally.

For example, I see:

PDF with invisible letters

Copying and pasting the start of the paragraph into another program, I see: "The instantaneous rate of change at".

How can I fix this?

I suffered from the same problem and found that just changing the font to something else then back to the original font fixed the issue.

Hope this helps.

This may have to do with the embedding of restricted fonts. Try unchecking the Acrobat Preference for "Use Local Fonts" for reading, under Page Display > Rendering, as shown in the image below (or in a very similar location, depending on the version of Acrobat):

Please try this,

  1. Open the document with missing letters in Acrobat.

  2. Needs to be done only once: Go to menu -> View -> Tools -> Print Production (It will add Print Production to the tools set on the right)

  3. Go to Tools (on the right) -> Print Production -> Preflight (It will open a small popup window with a lot of tech info on it) Click small button “Analyze and fix” on the Preflight popup at the right bottom corner, it will ask you to save the document, you can leave the same file name. It will ask to replace – click yes.

  4. It will take a while to analyze the document and fix all conflicts with fonts, etc. And it will make PDF document slightly larger.

  5. You can inspect fixed file and close Acrobat – document should be fixed and saved.

Hope that helps. (Using Acrobat XI Pro)
