--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
AFAICT the substring problem occurs for PARAMETER only:

program test3
  INTEGER,PARAMETER :: ucs4 = selected_char_kind("ISO_10646")
  CHARACTER(3,UCS4),PARAMETER ::
unip=CHAR(INT(Z'5e74'),UCS4)//CHAR(INT(Z'6708'),ucs4)//CHAR(INT(Z'65e5'),ucs4)
  character(3,UCS4) :: uni
  uni = unip
  open(6, encoding="utf-8")
  print *, uni
  print *, uni(2:2)
  print *, unip
  print *, "'",unip(1:1),"'"
end program test3

gives at run time
