Finding and replacing new line characters

I am making some string variables to use in an animation. Another person in the office has has written all of the text using Word. Some of these strings have up to 50 lines and each new line has some sort of special character in there which creates an arror in AS. I can manually go through and place the cursor at the end of the line at that point, hit delete and then type in “\r”. This eliminates the error but I have a lot of these strings, days of work. I have not been able do a simple find and replace. Has anyone experienced this before? Is there a way to use notepad++?

Any help would be great.
