UDF Read driver on Windows XP

Hi,

I have developed a Packet Writing (file system) driver on Windows XP for
CD-RW media. This driver also supports the UDF Read functionality. I am
able to copy English files and folders properly but when I try to copy a
Japanese or Korean file or folder, I get a error while writing.

When I debugged the code, I found that the problem was with the Read
functionality.

I am using the CDFS sample provided with the Microsoft IFS Kit as the
reference for the UDF Read functionality. Could anybody let me know what
could be the problem here ?

Thanks in advance for all the help.
