Yes.

But.

APPENDIX_C:_HOLLERITH

           The  character  data  type  was  added  to  provide   a
           character  data  processing capability that is superior
           to the Hollerith data capability that existed  in  ANSI
           X3.9-1966.

           The  Hollerith  data  type  has  been   deleted.    For
           processors   that   extend  the  standard  by  allowing
           Hollerith data, the following rules  for  programs  are
           recommended:

...

           C2.  Hollerith_Constant

           The  form  of  a  Hollerith  constant  is  a   nonzero,
           unsigned,  integer constant n_ followed by the letter H,
           followed  by  a  string  of  exactly   n _   contiguous
           characters.   The  string may consist of any characters
           capable of representation in the processor.  The string
           of n_ characters is the Hollerith datum.

           In a Hollerith constant, blanks are significant only in
           the n_ characters following the letter H.


           C3.  Restrictions_on_Hollerith_Constants

           A  Hollerith  constant  may  appear  only  in  a   DATA
           statement and in the argument list of a CALL statement.

VMS Fortran has always extended with this.
