Comment 2 for bug 456248

Not surprisingly I have the same kind of issue if I compress a file on Ubuntu (tar.gz or .zip) and try to open it on Windows, and vice versa (only 7zip format seems to work well).
Switching to lzma could be a solution, but it is not supported in the current Python version as a default module and I'm reluctant to add another external one.

I think that I will commit my current dev version, which uses cp437 on Windows and latin-1 on Linux and OSX. As long as you don't share the compressed file between these operating systems, it should work as expected.
Of course, if you don't use special characters in your path, there's no problem at all!
