Can you elaborate on this? Per spec, URL parsing doesn't invoke a decoder
but an encoder:
https://url.spec.whatwg.org/#query-state

Here's the corresponding code in Firefox using the span-oriented API that I
linked to in my previous email:
https://searchfox.org/mozilla-central/source/netwerk/base/nsStandardURL.cpp#138
The span-oriented API works well here in my opinion, even though this case
is a more advanced used of the API that implement a custom replacement
behavior.
