URI component encoding

Noun
DefinitionURI component encoding is the process of converting characters within specific parts of a Uniform Resource Identifier (URI), such as path segments or query parameters, into a format that is universally safe and unambiguous. This conversion, often called percent-encoding, replaces characters that have special meaning in a URI or are not allowed with a '%' followed by their hexadecimal ASCII values. Its primary purpose is to prevent misinterpretation of a URI by ensuring all characters can be properly transmitted across networks and systems. This process makes URIs robust and consistent.
Example

"When a search query contains spaces, URI component encoding transforms them into '%20' before appending them to the URL."
