How Emoji Works
Emoji originated in Japan in the late 1990s, with the term combining the Japanese words for 'picture' (絵, e) and 'character' (文字, moji). Initially proprietary to Japanese mobile carriers, emoji were standardized by Unicode Consortium starting in 2010, enabling cross-platform compatibility. Each emoji has a unique Unicode code point, and platforms render them using their own designs while maintaining semantic consistency. The Unicode Standard continually expands the emoji set, with categories including smileys, people, animals, food, activities, travel, objects, symbols, and flags. Emoji have become a universal visual language, transcending linguistic barriers in digital communication.
