  ## Examples



  This function also accepts a `predicate` function as an optional
  argument. If passed, this function will be called with each byte
  in `string` as its argument and should return a truthy value (anything other
  than `false` or `nil`) if the given byte should be left as is, or return a
  falsy value (`false` or `nil`) if the character should be escaped.
