Special_Characters

   Some ISO Latin-1 characters require the circumflex (^) to precede
   them in a file specification in order to be interpreted as
   literal characters rather than special function characters.
   The circumflex (^) is interpreted by the system as an escape
   character.

   o  The circumflex (^) followed by underscore (_) or by a space
      represents a space.

   o  The circumflex (^) followed by any of the following characters
      means that the character is to be used as part of a file name
      rather than having any special meaning that it might otherwise
      have in a file specification:

      .  ,  ;  [  ]  %  ^  &

   o  A user can enter a literal period (.) with or without the
      circumflex (^) in a file name. The system adds the circumflex
      to any periods other than those that act as delimiters for the
      file type and version number. Literal periods (.) in directory
      names must be preceded by the circumflex.

      File names containing special characters cannot be accessed
      from a VAX system.
