Fun Fact
The percent-encoding scheme uses hexadecimal values derived from ASCII and UTF-8 byte representations. This is why every encoded character begins with the "%" symbol.
Historical Context
URL encoding originates from early web standards defined in RFC 1738 and later refined in RFC 3986. It was introduced to ensure safe data transmission across different systems that interpret reserved characters differently.
