It's OK to redirect to the Main Page, but I was wondering if we could redirect

https://www.wikifunctions.org/view/en/Special:WhatLinksHere/Z802

to

https://www.wikifunctions.org/wiki/Special:WhatLinksHere/Z802?uselang=en ?

(Shall I file an additional task for that?)

Please do, though I worry about "search for something that looks like a ZID and redirect the user to that view page" when we don't (yet) display a notice that the user was redirected and why.

If we try to fix it we should also fix https://www.wikifunctions.org/view/en/w:test

I don't think that's related. I also don't agree that we should fix bad URLs like that.

Filed T343405 for the followup.

Redirecting to the Main Page is better than an exception, but… the whole behavior of that URL is strange. First, when being logged in with a non-English UI language, it does not redirect to the project main page, but to the (nonexisting) localized default main page name in the language. (E.g. for me, https://www.wikifunctions.org/view/en/Special:WhatLinksHere/Z802 redirects to https://www.wikifunctions.org/wiki/Hlavn%C3%AD_strana) When I tried to reproduce that, I went to https://www.wikifunctions.org/view/en/Special:WhatLinksHere/Z802?uselang=cs which… just shows the contents of Z802 directly? (As does https://www.wikifunctions.org/view/en/Special:WhatLinksHere/Z802?uselang=en, only the language differs… I guess there is an unsolved confusion between view/xx/... and ?uselang=yy there generally.)
