Started failing for valid link containing %28/%29 after release of link-check@4.5.3

[DavidAnson]

This worked 24 hours ago (I run CI nightly) with v3.8.3 and fails now with v3.8.4. However, downgrading to v3.8.3 does not help. Perhaps a dependency updated their patch version?

Downgrading to link-check@4.5.2 fixes the break.

I reproduced and confirmed the bug. I will investigate on the link-check side first.

Also fails on this link: https://research.web3.foundation/en/latest/polkadot/Token%20Economics.html#inflation-model

For those who uses markdown-link-check within gaurav-nelson/github-action-markdown-link-check/ Github Action I've had an issue with %20 in URL and had to workaround it with gaurav-nelson/github-action-markdown-link-check#85

I've encountered numerous failures in the last 2 days since the latest was pushed. As noted above all occurrences have URLEncoded elements.
Ex:

• In a regular browser (Firefox 83, Chrome 87, etc) access is just fine:

[tcort]

I've published version 3.8.5 which should solve this.

[TriplEight]

@tcort thanks, but it doesn't seem working: gaurav-nelson/github-action-markdown-link-check#86

[TriplEight]

$someone has fixed my example link https://research.web3.foundation/en/latest/polkadot/Token%20Economics.html#inflation-model and now I fail to find a good example with %20

[NicolasMassart]

It looks like gaurav-nelson/github-action-markdown-link-check#86 tests are successful.

The correct Polkadot link is https://research.web3.foundation/en/latest/polkadot/economics/1-token-economics.html#inflation-model, the one you provided is broken and is reported as broken by link-check not because of the % but because the page doesn't exist (deleted?) and was not redirected, that seems correct to me.

[TriplEight]

yes, the link was as I mentioned yesterday. Now I'll put https://www.google.com/?q=url%20with%20a%20space to a test. And yes, it's working.

[kingthorin]

Thanks, I've only been able to re-tests one occurrence but it does seem fixed.
