You would see the problem with any SMB server that does not support
the Unicode variants of the CIFS protocol.

The bug is specific to the older non-UNICODE variant of the CIFS 
protocol as implemented in the Windows clients.  The bug does not exist
for the UNICODE variant.

You do not need to put words in my mouth.

The bug is not an AFS problem but the bug will be avoided after the 
redirector based AFS client is implemented.

There are many projects that I wish to implement for OpenAFS that will 
make OpenAFS better for Windows users.  Those who wish to seem them 
implemented can help by finding financial resources with which 
developers can be paid.
