Fun Fact
ASCII originally supported only 128 characters, while Unicode now supports more than 149,000 characters across hundreds of languages, symbols, and emojis, making global digital communication possible.
Historical Context
ASCII was created in the early 1960s as one of the first standardized character encoding systems for computers. It provided a common way for machines to represent English letters, numbers, and basic symbols.
As computing became global, ASCII proved too limited for international languages. Unicode was introduced to solve this problem by creating a universal character set capable of representing virtually every writing system in the world. Tools like this one help bridge the gap between the classic ASCII standard and the modern Unicode ecosystem.
