I wasn't sure whether it was only [] that was handled specially, or the

So shell-quote-argument is indeed the correct thing.

I have no way to check this.  Looks like pkzip is Windows-only.

Well, archive-zip-extract already branches for pkzip/unzip, so whatever
uncleanliness that's associated with is already present...
