JSch to download file with file name in non ASCII characters
===

I am using JSch's ChannelSftp to download files from remote FTP server to local linux machine. When remote machine has file's with filenames which have non-ascii characters, downloaded file has ? instead of those non-ascii characters. 

For example a file with filename - test-測試中國人的字.txt present in the ftp server will appear as test-??????.txt after downloading on local machine.

Is there a way, I can retain the non-ascii characters after downloading or automatically convert them to something more meaningful.
