The encoding shouldn't be the issue (It is same when I have UTF-8 
and use \u00DF to represent ß). 
Anyway we succeeded to narrow the problem.

Now we have at hostname following two shares:
Shareß
ShareSS

Then following code:
new SmbFile("smb://hostname/Share\u00DF").exists();

will work, but only because the SmbFile instance actually represents
ShareSS and not the expected Shareß (we verified that by checking
the content of the retrieved share).

As mentioned there is a bug in Java, which uppercases ß character into SS
string. Therefore I assume that inside the JCIFS code is done uppercase
of the URL, which leads to this problem.

Thanks,
