TreeSize is able to zip files with file names including characters which are not part of your activated code page (Unicode file names). To restore this Unicode-decoded Zip files you will need an Zip tool able to handle Unicode encoding.
Here is a list of tools we have tested for Unicode compatibility:
•WinRAR (V3.8 or higher)
•WinZip (V11.2 or higher)
•7-Zip (V4.6 or higher)
•PeaZip (V5.1 or higher)
•BitZipper (V2013.13.4.16 or higher)
•IZArc (V188.8.131.5288 or higher)
•Windows integrated Zip tool (Windows 8 / Server 2012 or later)
Please note that the integrated Zip tools of Windows Vista, Windows 7, Windows Server 2003, and Windows Server 2008 are NOT Unicode compatible.
