Fun Fact
URL encoding was originally designed to safely transmit characters over early web protocols that only supported a limited ASCII character set. Today, it remains critical for modern APIs and web security practices.
Historical Context
The concept of percent-encoding emerged alongside the standardization of Uniform Resource Identifiers in the 1990s. As JSON became the dominant web data interchange format in the 2000s, combining JSON with URL encoding became essential for scalable API communication and client-side data portability.
