I have smbd version 3.6.6 on Linux and mount the share on a FreeBSD system with mount_smbfs. When I try to copy (cp) a filename containing a question mark, I will get the error: No such file or directoryRenaming the files would be obviously possible, but sadly they are saved html pages referencing each other and I would also have to change the source code.I know that question marks in filenames is a very bad style but aside from the samba-problem they don't cause any issues.Disabling or enabling the option display charset = utf-8 does not help.
Question marks in filenames and Samba
