[Samba] Problems with unicode filenames

[Cristian Thiago Moecke]

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 ç, ã, é 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
