Is there any way of distinguishing these Python-created ZIP archives from ZIP archives created by other Windows programs? Emacs by default assumes that file names in a ZIP archive created by a Windows program are encoded in the console codepage, and it enforces using that encoding for file names when the "creator" of the ZIP archive indicates the archive was created by Windows programs such as InfoZip's zip.exe and the File Explorer. In my testing, zip archives created by Python as above record the "creator" as number 0 (zero), which is identical to what InfoZip does. So, unless someone explains how to distinguish these zip archives from those created by InfoZip, I don't see how can Emacs know whether to use the InfoZip heuristics or the Python heuristics. Without the InfoZip/File Explorer heuristics we have in arc-mode.el today, Emacs on Windows would be completely unable to support non-ASCII file names in ZIP archives. ^ permalink raw reply [flat|nested] 9+ messages in thread

There is a bit flag indicating that the subfile name is encoded with utf-8. Bytes 6-7 in local file header or bytes 8-9 in central directory header are general purpose bit flag. And bit 11 of the flag represents file encoding flag(1 for utf-8 encoding). I guess unzip.exe does not support utf-8 encoded subfile name. Writing batch file with utf-8 encoding: c:\Emacs\emacs-29.1\bin\unzip.exe test.zip 一.txt and run with chcp 932, 荳\200.txt is extracted. With chcp 65001, extraction failed. Writing batch file with cp932 encoding:(same as above) c:\Emacs\emacs-29.1\bin\unzip.exe test.zip 一.txt and run with chcp 65001, 荳\200.txt is extracted. With chcp 932, extraction failed. This is not an ideal behavior, but extraction to STDOUT may work. To the contrary, 7z.exe extracts 一.txt correctly. If batch file is encoded with utf-8, it works with chcp 65001. If batch file is encoded with cp932, it works with chcp 932. ^ permalink raw reply [flat|nested] 9+ messages in thread

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. > I tried the settings below, but rewriting entries does not work. > (archive-zip-* variables' values are default if archive-7z-program is set > and zip.exe/unzip.exe are non-existent) > > (setq archive-7z-program "c:/Program Files/7-Zip/7z.exe" > archive-zip-extract '("c:/Program Files/7-Zip/7z.exe" "x" "-so") > archive-zip-expunge '("c:/Program Files/7-Zip/7z.exe" "d") > archive-zip-update '("c:/Program Files/7-Zip/7z.exe" "u") > archive-zip-update-case archive-zip-update) > > It is because update command needs "-si" option followed by an entry > name.

Sorry, I have mistaken something. 7z.exe works for rewriting with the settings above. (not only ascii subfiles but also cp932 encodable subfiles) I imagine if there is a special program which interprets ascii arguments into multilingual strings. Any subfile in any archive file will be treated correctly within emacs. So I implemented an instant program using base64.
