New ReactOS can zip/unzip files and folders in UTF-8 filenames. You can also choose the codepage of filenames to zip/unzip via the ZipCodePage / UnZipCodePage registry values on the registry key HKEY_CURRENT_USER\Software\ReactOS. Windows 8 or later also support UTF-8 zipped folders. You can also use 3rd party software to zip/unzip in older Windows. - Use <atlconv.h> for string conversion. - Use zipOpenNewFileInZip4_64 instead of zipOpenNewFileInZip3_64, and then add MINIZIP_UTF8_FLAG flag. - Set the filenames in UTF-8 by using CP_UTF8 codepage. - Codepage is user selectable via registry settings.
