How to write Emoji on image using imagettftext()?

Question

I want to use imagettftext() to put Emoji on image (some users use Emoji as username, such as Summer).

Answer 1

I'm trying to accomplish exactly the same, but based on cleong's answer at this post I'm assuming that I won't be possible.

Here is what he said:

I don't think it's going to work. GD doesn't currently recognize UCS-4 CMAP. It'll fall back to using a UCS-2 CMAP. Characters beyond the BMP aren't reachable.
