About URL Encoding/Decoding

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It converts special characters into a format that can be safely transmitted over the internet :cite[4]:cite[7].

When to Use URL Encoding

• When including special characters in query parameters
• When submitting form data via HTTP GET requests
• When handling user input that may contain reserved characters
• When working with APIs that require properly encoded parameters

Reserved Characters in URLs

According to RFC 3986, these characters are reserved and may need encoding: ! * ' ( ) ; : @ & = + $ , / ? % # [ ]

Unreserved characters that typically don't need encoding include: A-Z a-z 0-9 - _ . ~
