Traditionally, Unix/Linux/POSIX pathnames and filenames can be almost any sequence of bytes. A pathname lets you select a particular file, and may include zero or more “/” characters. Each pathname component (separated by “/”) is a filename; filenames cannot contain “/”. Neither filenames nor pathnames can contain the ASCII NUL character (\0), because that is the terminator. This lack of limitations is flexible, but it also creates a legion of unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws). It also makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users.
