Emoji doesn't render for typst \u{27A1}

[youwuyou]

I was trying to use the right arrow emoji, i.e with the escape code \u{27A1} named arrow.r.filled as specified under official typst document here and it does not seem to work unfortunately, while the other emojis are rendered correctly when I export the pdf.

Here is my web workspace view, it seems to me that the typst is using the "Right Arrow on Twitter / X Twemoji 15.0.1" variant instead?

Thanks for the great work!

Noto Color Emoji (the only font supported for now) does not implement it. And I don't why it should either: this symbol is a Black Rightwards Arrow... so no color ;)
One way to support it would be to add more symbols from Noto [] Emoji for instance.

PS: I don't see why Twemoji defines it in blue?!

my bad! will investigate it

After looking into it, it's "a feature not a bug"!

So yes \u{27A1} is not truly an emoji. A classic font may provide a classic fat arrow for it.
But the sequence \u{27A1}\u{FE0F} (variation selector 16) is definitely one.
Most emoji picker will input the sequence when asking for the right arrow.

I had to actually care about emoji sequences because for Noto Emoji: 0, 1, ... are emoji too .

IMO Typst should change the definition of #emoji.arrow.r.filled.
