Old versions of MediaWiki from before Special:Log was invented in December 2004 logged deletions to a wiki page instead. It looks like those old revisions also allowed titles with invalid UTF-8 to be saved, and then when such a title was deleted faithfully recorded it in the log ...

(The fact that it's a current revision rather than an old revision is not relevant - the page hasn't been edited since 2004)

This was marked known-bad.

I'm honestly impressed by how well MediaWiki handles a page whose current revision is bad ...
