     character(kind=ascii, len=26) :: alphabet
     character(kind=ucs4,  len=30) :: hello_world

     alphabet = ascii_"abcdefghijklmnopqrstuvwxyz"
     hello_world = ucs4_’Hello World and Ni Hao -- ’ &
                   // char (int (z’4F60’), ucs4)     &
                   // char (int (z’597D’), ucs4)
