Percent encoding examples seem to be wrong

[ChALkeR]

What is the issue with the URL Standard?

https://url.spec.whatwg.org/#example-percent-encode-operations:

Percent-encode after encoding with ISO-2022-JP, input, and the userinfo percent-encode set	"¥"	"%1B(J\%1B(B"

But https://url.spec.whatwg.org/#userinfo-percent-encode-set:

The userinfo percent-encode set is the path percent-encode set and U+002F (/), U+003A (:), U+003B (;), U+003D (=), U+0040 (@), U+005B ([) to U+005D (]), inclusive, and U+007C (|).

U+005B ([) to U+005D (]), inclusive

This includes U+005C (\)

It can't be left unescaped as the result of Percent-encode after encoding with userinfo percent-encode set

But it's present in the expected output in the example

It was that way since the introduction in e5334dd

Side note: Chrome disagrees with spec on ' not being included:

const u = new URL('https://example.com')
Array.from({ length: 128 }, (_, i) => String.fromCharCode(i)).slice(0x20, -1).filter((c) => (u.username = c, u.username !== c)).join('')

Refs: http://url.spec.whatwg.org/#set-the-username

Node.js:
' "#/:;<=>?@[\\]^`{|}'

Deno:
' "#/:;<=>?@[\\]^`{|}'

whatwg-url:
' "#/:;<=>?@[\\]^`{|}'

Safari:
' "#/:;<=>?@[\\]^`{|}'

Firefox:
' "#/:;<=>?@[\\]^`{|}'

Chrome:
' "#\'/:;<=>?@[\\]^`{|}'

They all agree on \ being included though

Thanks, that first thing does seem like I didn't double check something when I wrote that.

https://wpt.fyi/results/url/url-setters.any.html%3Fexclude%3D(file%7Cjavascript%7Cmailto) already shows Chrome being non-conforming for that so that seems covered specification and test-wise.

If you could take a look at #896 that'd be great.
