Can you explain what the Unicode standard is and what it is used for?

The Unicode Standard is a universal character encoding standard that allows for the unambiguous representation and processing of text in any language of the world. It assigns a unique numerical code (code point) to each character, including letters, digits, punctuation marks, special symbols, and even emojis.

Unicode is used to ensure compatibility and interoperability of text data across different systems, platforms, and programming languages. Thanks to Unicode, multilingual text can be displayed and processed correctly without loss of information.

In C/C++, Unicode handling often involves types like wchar_t, ICU libraries, or UTF-8/UTF-16 encodings, which implement Unicode character representations.
