+ * Represents a string of Unicode grapheme clusters encoded as UTF-8.

+ * 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.
