Struct CharacterBoundary 

pub struct CharacterBoundary { /* private fields */ }

A TextBoundary subclass for retrieving the range of the grapheme the given position is in.

The class is implemented using the unicode-segmentation crate, which supplies the same UAX #29 grapheme clusters as the characters package Dart uses.
