Fun Fact

Unicode assigns blocks not just for modern languages, but also for ancient scripts, musical notation, mathematical symbols, and even fictional writing systems.

Historical Context

Before Unicode, character encoding systems were fragmented and incompatible, often limited to 256 characters. The Unicode Standard, first published in 1991, unified global text encoding into a single system. Tools like this one build on that foundation, enabling precise and reliable manipulation of text across all languages and platforms.
