# Commentary:

# Convert charset map of various format into this:
#	0xXX 0xYYYY
# where,
#   XX is a code point of the charset in hexa-decimal,
#   YYYY is the corresponding Unicode character code in hexa-decimal.
# Arguments are:
#   $1: source map file
#   $2: address pattern for sed (optionally with substitution command)
#   $3: format of source map file
#	GLIBC-1 GLIBC-2 GLIBC-2-7 CZYBORRA IANA UNICODE UNICODE2 YASUOKA
#   $4: awk script

## So that eg [A-F] as used by KANJI-DATABASE branch below works as expected.
## Otherwise with LANG=en_US.utf8, CNS-6.map was generated with a
## bogus entry.  By experiment, LC_COLLATE=C was not enough.
