Unicode vs UTF-8 Explained: Why 'A' Is 65 and Emojis Break Code
Ever wondered why the letter A is secretly the number 65, or why a tiny cafe sign can crash a website? This is the whole story, explained in plain English with zero jargon.
We start in the 1960s with ASCII and its cramped 128 slots, then watch the entire world get locked out of computers. From there we meet Unicode, the giant catalog that gives every character on Earth a unique ID number, and UTF-8, the clever storage method that stretches from 1 to 4 bytes only when it needs to. Along the way you will finally understand why an accented letter needs more space than a plain one, what that garbled 'é' text really means, and why UTF-8 now runs about 99 percent of the web.
By the end you will know the one distinction that clears up almost every encoding bug: Unicode is the what, UTF-8 is the how.
