About Unicode

Unicode is a universal character encoding standard that assigns a unique number (code point) to every character across all languages and symbols. It supports over 140,000 characters from 150+ writing systems.

Unicode Basics

Code Point: Unique number for each character (U+0041 = 'A')
Planes: Unicode divided into 17 planes (0-16)
BMP: Basic Multilingual Plane (U+0000 to U+FFFF)
Astral Planes: Above U+FFFF (emojis, rare chars)

UTF Encodings

UTF-8: Variable 1-4 bytes, ASCII compatible
UTF-16: Variable 2 or 4 bytes
UTF-32: Fixed 4 bytes per character
Most Common: UTF-8 (web standard)

Examples:
'A' = U+0041 = UTF-8: 41 = UTF-16: 0041
'世' = U+4E16 = UTF-8: E4 B8 96 = UTF-16: 4E16
'😀' = U+1F600 = UTF-8: F0 9F 98 80 = UTF-16: D83D DE00
