Correction: '~' is legal. '/' is actually ':'.

  You are correct in a sense, but not in the context of the Finder. In the Finder, you see '/' instead of ":" and therefore "/" is a character that needs to be reserved for selecting files. But in the context of using the command-line, or (some?/most?) programming libraries, you would be correct.
