What emoji are
Emoji are the small pictures, faces, objects, symbols, and more, that people add to digital messages to express emotion, tone, and meaning. The word comes from Japanese, combining the words for picture and character, and is unrelated to the English word emotion despite the coincidence. From a simple smiley to a birthday cake, emoji have become a near-universal visual language layered on top of ordinary text.
Where they came from
Emoji originated in Japan in the late 1990s on mobile phones, where a designer named Shigetaka Kurita created an early set to add feeling to short messages. They spread worldwide after Apple included an emoji keyboard on the iPhone, first for Japan and then everywhere. As different companies made their own incompatible versions, it became clear that a shared standard was needed so emoji would work across all devices.
Emoji are actually text
Although they look like images, emoji are really text characters. They are part of Unicode, the universal standard that assigns a unique code to every letter, digit, and symbol used in the world's writing systems. Each emoji has its own Unicode code point, which is why you can send one in a message, copy and paste it, and even include it in a file name, just like any other character.
Why they look different everywhere
Unicode defines what each emoji means, such as grinning face, but not exactly how it should look. Each platform designs its own artwork for that meaning, so the same emoji appears a little different on an iPhone, an Android phone, and a Windows PC. Usually this is harmless, but occasionally a design difference has changed how a message was understood, which is why companies now keep their versions fairly consistent.
How new emoji are added
New emoji do not appear at random. The Unicode Consortium, the nonprofit that maintains the standard, reviews proposals and approves a new set roughly once a year. Anyone can submit a proposal, but it must make a strong case that the emoji would be widely used and is not redundant. Once approved, device makers add their own artwork, which is why a new emoji takes a while to reach every phone.
The bottom line
Emoji are standardized text characters, defined by Unicode, that render as small pictures to add emotion and meaning to messages. Born on Japanese phones and spread by the smartphone, they look slightly different on each platform because every company draws its own version of a shared meaning. Understanding that they are text, not images, explains how they travel so seamlessly across the devices and apps you use.
