Ruby regex: replace non-word chars that are not space chars

Question

How do I replace all non-word chars (\W) that are also not space characters (\s)?

This is the desired functionality:

"the (quick)! brown \n fox".gsub(regex, "#")

=>

"the #quick## brown \n fox"

Answer 1

"the (quick)! brown \n fox".gsub(/[^\w\s]/, "#")

By making the regex replace anything that is NOT a word character OR a space character.
