Uploading has been a chore. I now have to change my page breaks between chapters to section breaks and upload. Wish me well.
The issue seems to be with the occasional Italian word in my original file. They are used here and there throughout manuscript and are typed in italics. Nook's conversion has inserted new letters into one or two of these words and I can't figure why since they are not in the original file.
Any help would be appreciated.
If you are uploading a Word doc, it would be Word that's adding the characters, not the conversion.
You can export a Word doc to html (web page), then open the html in Sigil, a free & excellent download, and tweak it there.
