What is an emoji's Unicode code point?

Every emoji has a hexadecimal code point — for 🎉 it's U+1F389. Code points 0xFE00–0xFE0F are variation selectors that switch between text-style (▪) and emoji-style (🟦) presentations. Compound emojis (like flags, family groups, skin-tone variants) are sequences of multiple code points joined with ZWJ (U+200D).
