 
   ## Integer code points
 
-  Although code points could be represented as integers, this
-  module represents all code points as strings. For example:
+  Although code points are represented as integers, this module
+  represents code points in their encoded format as strings.
+  For example:
 
       iex> String.codepoints("olá")
       ["o", "l", "á"]
 
-  There are a couple of ways to retrieve a character integer
-  code point. One may use the `?` construct:

  @doc ~S"""
  Returns all code points in the string.

  For details about code points and graphemes, see the `String` module documentation.

  ## Examples


      "olá"

  Finally, to convert a String into a list of integers
  code points, known as "charlists" in Elixir, you can call
  `String.to_charlist`:

      iex> String.to_charlist("olá")
