Archive::Zip Global Variables
    $Archive::Zip::UNICODE
        This variable governs how Unicode file and directory names are added
        to or extracted from an archive. If set, file and directory names
        are considered to be UTF-8 encoded. This is *EXPERIMENTAL AND BUGGY
        (there are some edge cases on Win32)*. Please report problems.

            {
                local $Archive::Zip::UNICODE = 1;
                $zip->addFile('Déjà vu.txt');
            }
