We're seeing something similar coming back in the HP browse list,
which contains thousands of hosts.

I wondered if perhaps somebody had given a host a non-ASCII name, and
it was not being properly interpreted.  I'm not sure what the correct
interpretation would be, though -- is there any chance it could be in

At the moment the smbclient -L output scrambles the terminal
(requiring a reset(1)) by emitting 8-bit codes.  I wonder if it would
be better to have d_printf() escape these characters when translating
to ascii?
