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.
