Thanks, I installed the patch on the emacs-29 branch. I'm not
surprised that unzip.exe cannot extract such files, and I think it
works for you with 7z.exe by sheer luck: Windows transparently
converts non-ASCII characters to the system codepage when it invokes
programs via the "narrow" APIs, so it could mangle the UTF-8 encoded
file name into something unrecognizable.

Sorry, I don't understand: is this the same problem, or is this an
additional problem? For example, does rewriting entries work with
ASCII file names?
If this is a separate problem, I prefer that you submit a separate bug
report with all the pertinent details.
Thanks.
