libsmbclient supports the full UNIX character set
with SMB1+POSIX extensions.

So right now you can do this but you'd have to switch
back to SMB1+POSIX on the server, which isn't
recommended but will give you complete full
POSIX character set fidelity between libsmbclient
and Samba today.

Once we get SMB2+POSIX extensions done for SMB2
(after the server VFS rewrite) then a new Samba
smbd + new libsmbclient will support this natively.

Note that you'll won't get this to a Windows
server as these characters are reserved for
a Windows SMB implementation.
