   In general, the functions in this module rely on the Unicode
   Standard, but do not contain any of the locale specific behaviour.

  low-level manipulations of string, so let's explore them in
  detail next.

  ## Code points and grapheme cluster

  The functions in this module act according to
  [The Unicode Standard, Version 14.0.0](http://www.unicode.org/versions/Unicode14.0.0/).

  As per the standard, a code point is a single Unicode Character,
  which may be represented by one or more bytes.

  For example, although the code point "é" is a single character,
  its underlying representation uses two bytes:

      iex> String.length("é")
      1
      iex> byte_size("é")
      2

  Furthermore, this module also presents the concept of grapheme cluster
  (from now on referenced as graphemes). Graphemes can consist of multiple
  code points that may be perceived as a single character by readers. For
  example, "é" can be represented either as a single "e with acute" code point
  or as the letter "e" followed by a "combining acute accent" (two code points):

      iex> string = "\u0065\u0301"
      iex> byte_size(string)
      3
      iex> String.length(string)


      iex> "hello" <> " " <> "world"
      "hello world"

  The functions in this module act according to
  [The Unicode Standard, Version 14.0.0](http://www.unicode.org/versions/Unicode14.0.0/).
