Generally there is a bug for Windows Explorer on Chinese Windows Platforms that when decoding UTF-8 lines the last byte will be cut out and will ususally cause an error like a wrong filename. A work-around for this bug is to make the server using GBK and tell Windows not to use UTF-8. Currently Apache Mina FtpServer supports UTF-8 only, so I made this patch to make it possible to control it. Thank you for review the patch.
