You could probably use "filter txt with regex pattern", if you can come 
up with the right regular expression. One of our smart regex people 
probably knows what that is.

If you do end up using the function above, I think you'll want to use 
"and" instead of "or" in the "if" statement. As written it will match 
all possible characters.
