Unicode to Chinese conversion

① Unicode is a character set standard designed to provide a unified encoding scheme for all writing systems in the world.

② The goal of Unicode is to assign a unique code point to every character, regardless of the language, symbol, or emoji to which it belongs.

③ Unicode uses code points to represent each character. Code points range from U+0000 to U+10FFFF and can represent over 1,114,000 different characters.

④ Code points are typically represented in hexadecimal format, prefixed with U+.

⑤ In programming languages, Unicode characters can be represented using escape sequences.

⑥ For example, in JavaScript, you can use \uXXXX (where XXXX is the hexadecimal value of the code point) to represent characters in the Basic Multilingual Plane (BMP), and \u{XXXXXX} to represent characters in other planes.
