Wikipedia oneboxing of articles containing unusual characters in the URL

If you link to Wikipedia by reference, then the link works.

Филиппов, Михаил Михайлович (учёный)

If I copy the address from the browser line:

Филиппов — Википедия,%D0%9C%D0%B8%D1%85%D0%B0%D0%B8%D0%BB%D0%9C%D0%B8%D1%85%D0%B0%D0%B9%D0%BB%D0%BE%D0%B2%D0%B8%D1%87_(%D1%83%D1%87%D1%91%D0%BD%D1%8B%D0%B9)

Original address,_%D0%9C%D0%B8%D1%85%D0%B0%D0%B8%D0%BB_%D0%9C%D0%B8%D1%85%D0%B0%D0%B9%D0%BB%D0%BE%D0%B2%D0%B8%D1%87_(%D1%83%D1%87%D1%91%D0%BD%D1%8B%D0%B9)

Perhaps the error is not common, but in the last 2 days, users noticed that some Wikipedia articles (Russians) are processed in a similar way.

Perhaps because there is a comma in the link?


Same issue with ASCII-only titles containing commas:

I - Wikipedia,Robot(film),_Robot_(film)


The autolinker avoids certain extreme edge cases by design, last time I mentioned this to @Vitaly the general recommendation is to use <.......> here for terrible edge cases which allows you to workaround this. Does not work with one box though.

Current workaround is to swap , with %2c


Also weird when the Wikipedia URL ends in an exclamation point.!

You have to URL encode that as well…
