I was working in story editor on a book chapter today and realized that my text was peppered with the nonprinting symbol for bookmarks or hyperlinks, even though I've added none to the document (see image).
The text was placed from a Word document.
So seeing all these, I opened the bookmark panel and found a couple dozen bookmarks with the name OLE_LINK, numbered. I deleted them all but it looks like a lot of the nonprinting symbols are still there.
So what's the deal with these? I'm concerned that later on down the line when I produce an ebook that these might be a problem.
It's usually easiest to delete hyperlinks and bookmarks from within the original Word document.
My assumption was that these were being (wrongly) generated in ID. But after reading your comment I realized that someone had indexed the Word doc, and I didn't have bookmarks visible in Word. OK, problem solved...or at least explained.
