What encoding scheme is extensive to represent all the characters of all the languages in the world?

The Unicode encoding scheme is an extensive system that aims to represent all the characters of all the languages in the world. It assigns a unique code point (a number) to every character in the supported scripts.

Unicode is organized into several planes, which are further divided into code blocks, and finally, individual characters. The 17 planes in Unicode consist of the Basic Multilingual Plane (BMP) and 16 Supplementary Planes. BMP, the first plane, contains characters for almost all modern languages, while supplementary planes are used for historic scripts, symbols, and emoji.

Unicode has several advantages that make it extensive for representing characters of all languages: 1. Universal: Unicode supports over 1.1 million code points, which is large enough to accommodate characters from all writing systems in the world. 2. Evolving: Unicode is continuously updated with new characters and scripts as required, ensuring that it remains relevant and comprehensive. 3. Unambiguous: Each character in Unicode has a unique code point, eliminating the need for multiple encodings and reducing confusion. 4. Multilingual support: Unicode allows for the simultaneous representation of multiple languages in a single text, which is essential for global communication and sharing documents across different writing systems.
