grapheme

I'm trying to get the length of a javascript string in user-visible graphemes, ie ignoring combining characters (and surrogate pairs?). Is this possible, and if so, how would I go about it?

Are there any APIs or methods on String in Java that make it easy to count grapheme clusters? I've been hunting around but understandably the codePoints() method on a String includes not only the visible emojis, but also the zero width joiners. I also attempted
