For purity, no. For practicality, perhaps. It might be that some tools don't know how to unpack files marked as UTF-8, and always default to the system code page. OTOH, before accepting such a change, I'd like to know what actual existing tool would require such a hack, and a confirmation that this very tool indeed does not support UTF-8.

Just an example how I create and extract zip files with Russian filenames on Linux:

http://phdru.name/Software/Python/misc/zip.py.txt http://phdru.name/Software/Python/misc/unzip.py.txt

I hardcoded cp866 encoding to handle zip files the same way other tools (like WinZIP/WinRAR) handle Russian filenames. I hardcoded cp866 encoding into the code because it's the only encoding I've ever saw. cp866 is the OEM encoding in Windows; ANSI encoding is cp1251.

Oleg.
