/**
* Represents a string of Unicode grapheme clusters encoded as UTF-8.
*
* A letter followed by combining characters (accents typically) form what Unicode defines
* as a grapheme cluster: a character as humans mean it in written texts. This class knows
* about the concept and won't split a letter apart from its combining accents. It also
* ensures all string comparisons happen on their canonically-composed representation,
* ignoring e.g. the order in which accents are listed when a letter has many of them.
