// 关于UNICODE
Unicode工作原理:
Unicode是一种通用字符编码标准，为每个字符分配唯一的码点。
示例:
"A" → U+0041, Decimal 65, UTF-8: 41, UTF-16: 0041
常见用途:
- >调试编码问题
- >检查不可见字符
- >验证UTF-8/UTF-16字节序列
- >查找Unicode码点和区块
- >分析emoji编码

Q: What is Unicode?
A: Unicode is a universal character encoding standard that assigns a unique code point to every character from every writing system.
Q: UTF-8 vs UTF-16?
A: UTF-8 uses 1-4 bytes and is ASCII-compatible. UTF-16 uses 2 or 4 bytes and is used by JavaScript and Windows.
Q: What is BMP?
A: The Basic Multilingual Plane (U+0000 to U+FFFF) contains the most commonly used characters.
Q: How many characters?
A: Unicode supports 1,114,112 code points. Over 149,000 are currently assigned.
Q: Code point vs character?
A: A code point is the numeric value (e.g., U+0041). Some visible characters use multiple code points.
