About URL Encoding/Decoding

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances.

URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. URLs cannot contain spaces and certain other characters that are not allowed in URLs.

Characters that are URL encoded:

Reserved characters: ! * ' ( ) ; : @ & = + $ , / ? # [ ]
Unsafe characters: space % { } | \ ^ ~ [ ] `
Non-ASCII characters: é, ñ, ü and other international characters

Common uses of URL encoding:

Creating valid URLs with special characters
Passing parameters in query strings
Submitting form data with the GET method
Encoding data for AJAX requests
Creating links with non-ASCII characters

Examples of URL encoding:

Space character: "Hello World" → "Hello%20World"

Special characters: "10% discount" → "10%25%20discount"
