[Haskell-beginners] Showing control characters

Is there some way to include control characters in a Show string so that
they take effect when the element is Shown?

For example, if I define a String "a\nb" and use putStrLn on it, the \n
causes a return, but when I simply return the string from a function, the \n
is shown as \n.  Is there a way to get the \n to execute when it's embedded
in a returned value?
