23# Comment:
24# Add a sort key 0, 1, 2, or 3 at the tail of each line as a comment
25# to realize the round trip mapping to Unicode works as described in
26# this page:
27# http://support.microsoft.com/default.aspx?scid=kb;EN-US;170559
28# Each sort key means as below:
29# 0: JISX0208 characters.
30# 1: NEC special characters.
31# 2: IBM extension characters.
32# 3: NEC selection of IBM extension characters.
a9cf9d0d 33# 4: user defined area
