I searched around can't find answer. or someone told me -mcp or -cp can do , but my version of 7z don't have. when I want to extract a 7zip file with Japanese or chinese file name, it got garbled. there is a ridiculous solution out there tell me to change the whole windows coding to japanese and reboot to extract japanese zip, after that change the whole windows to chinese encoding to chinese reboot and extract chinese zip. and repeat.... I wonder is there is a command line switch can force the filename...
