defmodule Unicode.GeneralCategory.Derived do
  @moduledoc """
  For certain operations and transformations
  (especially in [Unicode Sets](http://unicode.org/reports/tr35/#Unicode_Sets)) there is an
  expectation that certain derived general
  categories exists even though they are not
  defined in the unicode character database.

  These categories are:

  * `:any` which is the full unicode character
    range `0x0..0x10ffff`

  * `:assigned` which is the set of codepoints
    that are assigned and which is therefore
    equivalent to `:any` - `:Cn`. In fact that is
    exactly how it is calculated using `unicode_set`
    and the results are statically copied here so
    that there is no mutual dependency.

  * `:ascii` which is the range for the US ASCII
    character set of `0x0..0x7f`

  """
