The patch from #4515 does little to provide a functional UTF-8 FTP
It is there only to help advertise future implementation of UTF-8 support.

Thanks for reminding about #5411 . I have submitted a patch for review
together with required tests.

I have a few more FTP ticket in work/waiting for review. As soon as
they are done, I will look at UTF-8 support.


Patch #4515 is already in trunk, and together with patch for #5411 it
should be a good start for UTF-8 support.

Ticket #5100 is mainly about the default IFTPShell implementation, but
if you have your own IFTPShell implementation just make sure it
accepts input as str encoded utf-8 and that it output str encoded
