* Add the :func:`~unicodedata.iter_graphemes`
function to iterate over grapheme clusters according to rules defined in
`Unicode Standard Annex #29, "Unicode Text Segmentation"
<https://www.unicode.org/reports/tr29/>`_.
Add :func:`~unicodedata.grapheme_cluster_break`,
:func:`~unicodedata.indic_conjunct_break` and
:func:`~unicodedata.extended_pictographic` functions to get the properties
of the character which are related to the above algorithm.
