UTF-8

Encoding & Standards

A variable-width Unicode encoding that uses 1 to 4 bytes per character, dominant on the web (used by 98%+ of websites).

UTF-8 is the most widely used Unicode encoding. ASCII characters (U+0000 to U+007F) use 1 byte, making it backward-compatible with ASCII. Characters beyond ASCII use 2-4 bytes.

Most emoji require 4 bytes in UTF-8 because they live in the Supplementary Multilingual Plane (code points above U+FFFF). For example, 😀 (U+1F600) encodes as 0xF0 0x9F 0x98 0x80.

UTF-8's dominance on the web (recommended by W3C, used by HTML5 by default) makes it the standard choice for storing and transmitting emoji in most applications.
