You are about to embark on a journey to the forefront of human communication in the 21 st century: emoji. Consider yourself an early adopter. Emoji originated in Japan and, as such, they’re tightly coupled with the country’s traditions, food, and culture. But since being adopted into Unicode (an effort to standardize how software interprets and stores letters and characters) and integrated into smartphones, they’re now everywhere, used around the world by young and old alike. Sometimes they communicate our feelings when text won’t do, other times we use them to tell stories, and sometimes we just like to test our friends and family with emoji puzzles.
