Yes, at least for DataInputStream and DataOutputStream (which I suspect is
used by InputStreamReader for UTF-8 somehow) a length marker is prepended.

No, this is probably an artifact of integer overflow. The value -3 is 65535.

Are you sure it's Shift_JIS? Perhaps it's UTF-8. Pipe the output to
hexdump -c and post it.

You must consider that the terminal must convert the output to an encoding
suitable for display. If smbclient is really outputting Shift_JIS then
locale of the terminal must be changed to accomodate that. I don't know
how you would do that with a KDE terminal but you might try xterm -u8. In
other words, it might all be working, but you don't know it because you
cannot display it. Even if you get the encoding right you still need a
Japanese font!

You definately don't want to use readUTF. That's "modified" UTF-8. See the
API docs for DataInput.readUTF.
