   As we have seen above, code points can be inserted into
   a string by their hexadecimal code:
 
-      "ol\u0061\u0301" #=>
+      iex> "ol\u00E1"
       "olá"
+
+  Finally, to convert a String into a list of integers
+  codepoints, usually known as "char lists", you can call
+  `Strig.to_charlist`:
+
+      iex> String.to_charlist("olá")
+      [111, 108, 225]
 
   ## Self-synchronization
 

  @moduledoc ~S"""
  Strings in Elixir are UTF-8 encoded binaries.

  ## Code points and grapheme cluster

  The functions in this module act according to the Unicode


  In general, the functions in this module rely on the Unicode
  Standard, but do not contain any of the locale specific behaviour.
  More information about graphemes can be found in the [Unicode
  Standard Annex #29](https://www.unicode.org/reports/tr29/).

  For converting a binary to a different encoding and for Unicode
  normalization mechanisms, see Erlang's `:unicode` module.
