[jcifs] Encoding Problems under Linux ?

[Michael B Allen]

There are a number of places where the encoding of path names can be
different. You have the remote filesystem, then the server may translate
that into a different encoding, the client might then translate it
again, the client's internal encoding, and then the client filesystem
encoding. It sounds like you're not concerned with the last three
possibilities and if the remote server is really a Windows machine
running NT or above then the remote server will send Unicode (unless
you have useUnicode set to false). So in all likelyhood you need only
tweek the jcifs.encoding property but the defaults should work.

Try setting jcifs.encoding to CP850. Note that some JVMs do not ship with
CP850 support. See the notes in the API documentation about this property.
