Unicode Encoding Explained: Code Points, UTF-8, UTF-16, and UTF-32 Unicode is the universal character set. Every character you'll ever need — from Latin letters to Klingon script to emoji — has a code point in Unicode. But a code point is just a number. To store or transmit text, you need an encoding that turns those numbers into bytes. That's where UTF-8, UTF-16, and UTF-32 come in. This article explains the fundamentals precisely, so you understand what's actually happening when your code reads, writes, or converts text. --- Code Points: The Foundation A Unicode code point is an integer from 0 to 1,114,111 (0x10FFFF).
