Fun Fact
UTF-8 can represent over one million possible Unicode code points while remaining backward-compatible with plain ASCII-a major reason it dominates the modern web.
Historical Context
UTF-8 was introduced in 1992 to solve the fragmentation of character encodings across systems and languages. Its variable-length design allowed global text representation without breaking existing ASCII-based software, leading to its widespread adoption as the default encoding of the internet.
