search for: charsert

I have a file server with windows and I am creating a new Fedora Core 3 + Samba 3.0.10-1.fc3 file server... But i have many, many files that have chars like ?, ?, ? in their name... When I move the files to the Samba server, all that unicode chars are changed to ? I need a solution for that to move on, because my boss will not like to stop using that chars... Thanks for any help Cristian
