Thanks for this work.

It is kind of surprising that "Windows builtin" has very poor score extracting from the output of Zip tools running on Windows (I am looking at 46, 46 and n/a over there). If you tell it to create an archive from its disk and then extract from it, I wonder what would happen.

Does this result mean that practically nobody uses Zip archive with exotic letters in paths on that platform? I am not talking about developers and savvy people who know where to download third-party Zip archivers and how to install them. I am imagining a grandma who received an archive full of photos of her grandchild in her Outlook Express or GMail inbox, clicked the attachment to download it, and is trying to view the photo inside.
