I was looking more into how Swift detects extended grapheme cluster boundaries and came across these two functions:
_opaqueCharacterStride() which calls
I was wondering if someone could explain why the two functions seem to be used in different areas and are not used together (from what I could find in the source, but definitely could have missed something)? It looks like
_hasGraphemeBreakBetween() is an implementation of the Grapheme Cluster Break Specification. This left me confused about
isOnGraphemeClusterBoundary() which does not interact with
If anyone knows what these two functions do that would be super helpful! Thanks!
