URL unencoding

Noun
DefinitionURL unencoding, also known as URL decoding, is the computational process of converting URL-encoded characters back into their original form. When data is transmitted as part of a URL, certain characters that are not permitted or have special meaning (such as spaces, ampersands, or slashes) are replaced with a percent sign (%) followed by two hexadecimal digits. Unencoding reverses this transformation, restoring these percent-encoded sequences to the characters they represent. This operation is essential for web servers and applications to correctly interpret user-submitted data, file paths, and other information contained within a URL, ensuring that the received data is accurate and usable.
Example

"Before the search engine could process the user's input, it performed URL unencoding on the query string to correctly interpret the special characters."

Etymology & Word Origins

The term 'URL' is an acronym for Uniform Resource Locator, coined during the development of the World Wide Web. 'Unencoding' is formed by combining the prefix 'un-' (meaning to reverse an action) with 'encoding' (the process of converting information into a particular format), referring to the reversal of the URL encoding process.
