Reply To: What is this hidden character?

Thank you, Bala, for your reply. It doesn’t (yet) answer the question, but it may give a clue to someone else who can move me closer to an answer.

When I go into the story editor, I get this:

I don’t know what those three symbols represent and am intrigued that there are three of them, particularly as this seems to be the case in every instance where this hidden character (or characters) shows up. I have also noticed that, in every instance, it is at the beginning of a paragraph that has the same paragraph style, “Reference”. I have gone through the paragraph style details but can see nothing that arouses my suspicion.

Any more suggestions?
