quote :: String -> String

quote adds double quotes around the string, replaces newline characters with n, and escapes double quotes and backslashes within the string. This is different from the behaviour of show:

> putStrLn $ show "\x2200"
"\8704"
> putStrLn $ quote "\x2200"
"∀"

(The code examples above have been tested using version 4.2.0.0 of the base library.)
