What is Unicode?
Unicode is a universal character encoding standard that assigns a unique number to every character across all languages and scripts.
UTF-8
UTF-8 is a variable-width encoding using 1-4 bytes per character. It's the most widely used encoding on the web.
UTF-16
UTF-16 uses 2 or 4 bytes per character. Commonly used in Windows, Java, and JavaScript.
Code Point
A code point is a numerical value that maps to a specific character in the Unicode standard (U+0000 to U+10FFFF).
