What is Unicode?

Unicode is a character encoding standard designed to include almost all writing systems in use today, enabling the consistent representation and manipulation of text across different platforms and devices. It provides a unique number for every character, regardless of the platform, program, or language, which helps ensure that text appears the same everywhere. This standard supports characters from various languages, mathematical symbols, and even emoji, making it essential for developing software that is accessible to a global audience.

The other options do not accurately describe Unicode: a coding system for graphics focuses on visual data; encryption is related to securing data rather than representing characters; and a programming language for internationalization suggests a tool for development rather than a standard for character encoding.
