Xray

Xray is an academic exploration of strings and encodings in Elixir.

It offers utility functions useful for inspecting strings and their code points.

For example, the Xray.inspect/1 function:

iex> Xray.inspect("cät")

    ======================================================

    Input String: cät

    Character Count: 3

    Byte Count: 4

    Is valid? true

    Is printable? true

    ======================================================



    c   Codepoint: 99 (\\u0063) https://codepoints.net/U+0063

      Is printable? true

      Script(s): latin

      Byte Count: 1

      UTF-8: <<99>>

      Base2: 01100011



    ä   Codepoint: 228 (\\u00E4) https://codepoints.net/U+00E4

      Is printable? true

      Script(s): latin

      Byte Count: 2

      UTF-8: <<195, 164>>

      Base2: 11000011 10100100



    t   Codepoint: 116 (\\u0074) https://codepoints.net/U+0074

      Is printable? true

      Script(s): latin

      Byte Count: 1

      UTF-8: <<116>>

      Base2: 01110100

    [:ok, :ok, :ok]
