Letters disappear when editing (multiple Acrobat versions on PC)

I have multiple clients trying to edit PDFs, and when they do individual letters seem to randomly disappear. This is happening on Windows, on two different versions of Acrobat (Acrobat DC Perpetual Version 2015.006.30033 and Acrobat XI Version 11.0.0). We can not replicate the problem on Mac OS with DC Pro 2017 release.

Any ideas as to why this is happening and how to prevent it?

We are not merging documents, just using the edit PDF tool to copy and paste elements from other PDFs. The affected text boxes are not the ones being copied/edited.

Are the letters that disappear always paired ligatures? Like fi, fl, th, tt, ff, and such like pairs?

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)

4. 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.

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

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

Hope that helps. (Using Acrobat XI Pro)

This solution removed all color from my PDF and didn't fix the missing letter issue (in my case, all t's and i's are missing).

When you say you are not merging, you are probably referring to the problem described here: Workaround for Missing Characters After Merging PDF Files

It is possible that you are dealing with the same root cause, but the effect does not show up right away, and you have to actually try to add new content (or modify content) to the file. Would you be able to share one of these files?

I have previously tried the workaround in that link and it didn't work in this instance, which is what led me to believe it is a different issue.

I am unable to share a PDF because the content is proprietary, and we haven't been able to replicate the problem to create a dummy example file.

Without access to the file it's impossible to say why this is happening. It has to do with something in this particular file. Chances are that the file is corrupt.

You do have Adobe Acrobat Pro, so you can try the preflight tools to see if checking for syntax errors or for font errors will turn up anything. You can also try to see if fixing potential font problem will cure the problem.
