I have been noticing two rather "strange" text elements in Emacs which occur when I copy text. I am certain they signify something/have a special formatting purpose, but I am unable to find anything on the web. The first one is a blue dash and the second one a purple box. Since images are more illuminating here, I have created a screenshot:
Please forgive me my terrible editing skills.
Does anyone know whether it is possible to find all of these elements (they are recurring) by way of search/replace-string to eliminate them effectively? Otherwiese I cannot include them in LaTeX documents.
