Reference notes

Escaping values for URLs and APIs

Query values

Encoding prevents spaces, ampersands and symbols from breaking query strings or request URLs.

Percent encoding

Decoded output helps inspect copied links, redirect URLs and API callback parameters.

Component based

Formalint uses component encoding, which is appropriate for query values and path fragments.
