The Science of Percent Encoding
Percent-encoding, also known as URL encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. It is essential for sharing complex data through web addresses.
Why is it needed?
Certain characters have special meanings in URLs (like `?`, `&`, or `=`). If you need to include these as literal text, they must be "escaped" into their hex-based percent equivalents (e.g., a space becomes `%20`).
