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. |---|---|---| | Plane 0 | U+0000–U+FFFF | Basic Multilingual Plane (BMP) | Most scripts in active use | | Plane 1 | U+10000–U+1FFFF | Supplementary Multilingual Plane | Historic scripts, emoji, musical notation | | Plane 2 | U+20000–U+2FFFF | Supplementary Ideographic…
