Hello Steven!

Thanks for your reactivity!

    Returns the GraphemeBreakProperty assigned to the character chr as string.

====

unicodedata.break_graphemes() takes a unicode string as argument and returns an GraphemeClusterIterator that spits consecutive graphemes clusters.

help(unicodedata.break_graphemes) says:

break_graphemes(unistr, /)
    Returns an iterator to iterate over grapheme clusters in unistr.
    
    It uses extended grapheme cluster rules from TR29.


Is there anything else you would like to know? Don't hesitate to ask :)

Thank you for your time!
