findClusterBreak(str: string, pos: number, forward = true, includeExtending = true): number

Returns a next grapheme cluster break after (not equal to) pos, if forward is true, or before otherwise. Returns pos itself if no further cluster break is available in the string. Moves across surrogate pairs, extending characters (when includeExtending is true, which is the default), characters joined with zero-width joiners, and flag emoji.

isExtendingChar(code: number): boolean

Query whether the given character has a Grapheme_Cluster_Break value of Extend in Unicode.
