6 New Emoji
Every year, the Unicode Consortium develops a set of new emoji characters. These standardized emojis are then adopted by the various device manufacturers and operating system makers. Not every iOS update sports new emoji, but iOS 12.1 does.
All in all, there are about 70 new characters. That includes new red-haired, gray-haired and bald emoji; new expression and symbol emoji; and a variety of animals, food products, sports characters, and others.
