These functions specifically assume ascii.  For Fortran 2003:

  The intrinsic functions LGT, LGE, LLE, and LLT (13.7.63-13.7.66)
  provide comparisons between strings based on the ASCII collating
  sequence.  International portability is guaranteed if the set of
  characters used is limited to the letters, digits, underscore,
  and special characters.

See also Note 4.15:

  The intrinsic functions ACHAR (13.7.2) and IACHAR (13.7.45)
  provide conversion between characters and corresponding
  integer values according to the ASCII collating sequence.
