Match all control characters but line break \n

Question

Is there a way to write a regex that matches any control character except the line break "\n"?

I can write a regex to catch any of the control characters like so:

/\p{Cc}/

Answer 1

str = "Q\cA\n\cD%\cH\n"       #=> "Q\u0001\n\u0004%\b\n"

str.gsub(/[^\p{Cc}]|\n/, '')  #=> "\u0001\u0004\b"

Note that

"\cH" #=> "\b"

Answer 2

This should do it:

/(?!\n)\p{Cc}/

Negative lookahead, shouldn't match line breaks
