Obviously, filesystem driver layer does not care about this, it returns an 
"invalid argument" if you try to create a file containing a '?' on an ntfs 
filesystem. And Dolphin simply seems to forward that error to the UI.

I don't agree, especially if you do not know in advance that the files on some 
filesystem should be ever moved to another file system with different naming 
rules. Unix/Linux allows almost all characters, while other OS do not. Other 
file systems may have problems with UTF8, so with that argumentations, we 
should use DOS compatible 8.3 naming schemes, 7-Bit ASCII only, just do be 
sure. 

IMHO, a GUI based user program should be able to handle such cases, as most 
users do not care about such restrictions and assume its OK when their primary 
OS accepts it.
