  23 # Generate a translation table for CP51932 (EUC-JP of MicroSoft Version).
  24 # It maps invalid JISX0208 code points used by CP51932 to Unicode.
  25 # 4th field of the input has these meanings:
  26 #   0: JISX0208 characters.
  27 #   1: NEC special characters.
  28 #   2: IBM extension characters.
  29 #   3: NEC selection of IBM extension characters.
  30 # Among them, 1 and 3 are the target characters.  2 should have
  31 # already been mapped to 1 or 3.
