But Ada is already Unicode, which incorporates all possible schemes. I
don't see why there should be any platform dependence here. When a file
name is illegal there is already Name_Error exception here.

Applications practically never generate file names from scratch. They
compose them out of existing elements, such as directory path, simple name,
extension, user input. They just do not need to know anything about how
file names get ultimately encoded on the disk.

(Ada.Directories could provide some Character_Set (Wide_Wide_Character)
constants for valid file name characters etc.)
