Codes that appear in Tools, Action, Create Comment Summary

I use Acrobat Pro XI  to highlight important PDF documents. Then I like to extract those highlights to put in Evernote with the PDF below it. I have copy highlighted text into comments highlighted. I then use Tools, Action, Create Comment Summary to export to an Excel file and then move that into Word. The problem is I have these codes that appear, like "\r" and greek characters. I have a macro that does find and replace to change them into the appropriate characters / styles, like bulleted text or quotation marks. However, would love if there was some table that shared what each code was in real characters.
