Yes, I tested pasting "🍤" to my OSX, and was surprised by a color rendering of a friend shrimp.

(yes, you can copy the character between "" and paste in your OSX terminal)

Shame this doesn't work in zsh.

Why wouldn't it work on zsh? The font face is a property of the terminal emulator (e.g. xterm, Terminal.app), not the shell.

echo 🍤

fried!
