Hello, 👋 Is there a way to identify extended grapheme clusters?
👩‍👩‍👧‍👧 👍🏽 <- My use case is detecting first user perceived character in a String

[Ryan]

can you elaborate some more

[Attila Blenesi]

String[0] in the cases I posted return the first section of the unicode character that the emote is composed of :

val text = "👩‍👩‍👧‍👧 user perceived characters 👍🏽"
print(text[0])

?

👩‍👩‍👧‍👧 = \u200D\uD83D\uDC69\u200D\uD83D\uDC67\u200D\uD83D\uDC66
Android Studio does not support Zero Width Joiner characters so it look like this in the IDE:

unicode takes up more than one position in a string

[Attila Blenesi]

Yeah, I'm asking because I did not see any clear way to achieve this in Kotlin / Java / Android (the question posted is web specific.)

[Attila Blenesi]

I happy to create a Stack Overflow question myself.

Seems like https://developer.android.com/reference/android/icu/text/BreakIterator might be what I need

[Attila Blenesi]

This was

Added in API level 24

So would still need something backwards compatible

[Gonçalo Palaio]

Nothing is simple when dealing with emoji and I’m probably missing the point but couldn’t you loop through the codepoints and find the zero width joiners?

[Attila Blenesi]

You are right to some extent, there are some cases where zero width joiners are not present.
