You have the call center part right. My examples are only snippets of the full comments. Each line has a 65 character limit. 5 (or 6) lines per comment screen. Continuous typing and/or tab takes you to the next line.

One of my initial thoughts was spaces. A couple of the comment errors were found on orders I had created ages ago - I have a tendancy to space twice between words - my mind goes faster then my fingers... Where some of these characters are found in "empty" space - where it looks like someone may have hit the space bar two or three times. Your suggestion of it being a terminator sounds valid - I can see it being a strong possible. It still doesn't explain the cent sign and exclamation mark.

Thank you for your help Wige! It gave me a new direction to go.
