Character Encoding for Beginners: From Bits to Readable Text Computers store everything as numbers. Characters — letters, digits, punctuation, emoji — are numbers too. Character encoding is the system that maps those numbers to the characters you see on screen. Without it, the bytes are meaningless. With it, they're "Hello." This guide explains character encoding from first principles, clearly and without jargon. --- Bits and Bytes A bit is the most basic unit of data in a computer: a single binary digit, either 0 or 1. A byte is 8 bits. Eight bits can represent 2^8 = 256 distinct values: from 0 (00000000 in binary) to 255 (11111111 in binary). Everything stored on your computer — images, videos, source code, text files — is ultimately a sequence of bytes. --- The Problem: Bytes Have No…
