Unicode-aware JS string splitting, typescript version
npm install runes2> Unicode-aware JS string splitting with full Emoji support.
Split a string into its constituent characters, without munging emoji and other non-BMP code points.
this is typescript version fork form runes
The native String#split implementation does not pay attention to surrogate pairs. When the code units of a surrogate pair are split apart, they are not intelligible on their own. Unless they are put back together in the correct order, individual code units will cause problems in code that handles strings.
