BFile Issue

Hey Everyone, Maybe you can help me out...

I have been using Oracle BFiles to enable access for a files server and it usually works just fine. The problem started when people began
creating Unicode Filenames, which from some reason can't be accessed.

Doing a bit of testing I can see that the files are saved currectly on the
File-System (they can be viewed in their native language) and also on the DB
(I wrote a small ODP.NET program that displays the problematic file-names,
they seem right).

However something still doesn't work (when I call open() on the BFile object
it throws Exception that it can't find the file, this happens in programs
like Navigator 4 as well).

Ever encountered this? Doesn't BFiles support Unicode?

Thanks.
