we would have to update the text to say in what order it should be read

Sorry, I am not sure I follow. Can you elaborate? With this fix, the emojis would be read the same whether the user reads from RTL or LTR. Isn't that what we want?

The UI says 'ensure they appear in the same order', but wouldn't a RTL user read the emojis from right to left? In that case, the 'first' one in LTR would be the leftmost one and in RTL the rightmost one, right? I'm not a RTL user myself, so I'm not sure if that's the case.

I see the point now. I'm wondering how we handle this on iOS and web. I sort of assume the same user would casually see that emojis look the same regardless of what language is set but I could be really wrong here. :sweat_smile:

This is an interesting UX question.

Edited: Just checked this in Persian on iOS, fwiw, with this change, the emoji would in the same order on iOS and Android.
