When I export from DC to Word (or other programs), all words with repeated characters, such as "attributes" or "accomplishments," appear like this:
"at ributes", "ac omplishments," etc., missing the second character. This happens in all my programs, so it's not a problem at that end. It's something strange with DC. To say the least, it's a substantial burden trying to fill in the missing characters in a multi-page doc.
It sounds like a typeface problem. What typeface is being used? Do you have it on your system?
Try this: create a PDF with a typeface you know you have. Then export from Acrobat DC to Word. Does it still happen?
What settings are used when the PDF is created?
