What is UTF-16 Encoding?

UTF-16 is a variable-width character encoding for Unicode, using 16-bit (2-byte) code units. It can represent over a million characters, making it ideal for international text. Common in Windows, Java, and JavaScript.

How it works: Basic characters (BMP) use one 16-bit unit; supplementary characters use surrogate pairs (two units).

Use cases: Decoding API responses, file contents, or JS strings like '\uD83D\uDE00' to emojis πŸ˜€.
