Grapheme clusters are "user-perceived characters" - what a user would consider a single character, which may consist of multiple Unicode codepoints (e.g., a base character with combining marks, emoji sequences). :param unistr: The Unicode string to segment. :param start: Starting index (default 0). :param end: Ending index (default len(unistr)). :yields: Grapheme cluster substrings.
