docs: Provides an iterator over the *code points* of the given Unicode sequence.
  
      Notes:
          Before PEP-393, Python has the potential to support Unicode as UTF-16 or UTF-32.
          This is reified in the property as ``sys.maxunicode``.  As a result, naive iteration
          of Unicode sequences will render non-character code points such as UTF-16 surrogates.
  
      Args:
          val (unicode): The unicode sequence to iterate over as integer code points in the range
              ``0x0`` to ``0x10FFFF``.
