The context is a file name, in which you need something that a user
can input which is capable of representing path components that
contain arbitrary characters. Currently, a Unix path always interprets
a slash as a directory separator, so there's no way to have a slash in
a file or directory name. If you want to have *every* component
capable of containing *any* character, you either need a string to be
able to represent two strings, or you need some sort of escaping
mechanism.
