# Commentary:

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