It seems to work as expected. Can you specify the output you got vs. what you expected to get?

N.b. there is one thing that is a bit unclear in CyberChef however: the "URL Encode" op has "Encode all special characters" toggle, which seems to mean "work like JavaScript's encodeURIComponent as opposed to encodeURI") but there is no corresponding toggle for "URL Decode". And I wish it borrowed the "URI" vs "URI component" language from JS, if they are in fact the operations it uses.
