I have a ePub book in InDesign and I am exporting for digital editions. I have several files in the InDesign Book. One of those files is exporting quotation marks and the like into those special characters that html displays as weird characters. Only the one file is affected. The same quotations, etc., are in several if not all of the other files, and they display fine. The problem shows up in multiple readers. Any ideas what would cause the one file to export differently than the rest?
