About URL encoding

URL encoding (also called percent-encoding) replaces characters that have special meaning in URLs or are not allowed in the ASCII character set. For example, a space becomes %20, an ampersand becomes %26, and non-ASCII characters like é become their UTF-8 byte sequences in percent-encoded form.

Proper URL encoding is essential for query parameters, form data, path segments containing special characters, and any URL that includes user input. Incorrect encoding is a common source of broken links, failed API calls, and security vulnerabilities like open redirects.
