[jcifs] UnsupportedEncodingException: UnicodeLittleUnmarked

This is very strange that your Java implementation does not support the UnicodeLittleUnmarked encoding.
Try running a little program like:

byte b[] = { 0x41, 0x00, 0x42, 0x00, 0x43, 0x00 };
String s = new String( b, "UnicodeLittleUnmarked" );
System.out.println( s );

This should print ABC. If it gives you an exception you'll have a good test to track down the problem with.
Otherwise setting file.encoding alone will not prevent Unicode from be used. You would also need to set
useUnicode=false. But this isn't really the correct way to deal with the problem and it still won't work
because even though jcifs trys to abstract the encoding there are a few places where
"UnicodeLittleUnmarked" is used regardless of wheather or not Unicode is negotiated with the server.
