//   1. Its name is spelled wrong: "Charater"
//   2. "newline" in this context is a single word and should be capitalized as "Newline" not "NewLine"
//   3. Its name is misleading because it also escapes double quotes.
//   4. It escapes newlines using "l" rather than the more customary "n".
// I would just remove it, but it seems to be used in some projects and the tutorial.
