Update CJK converters and their generating scripts

source/data/mappings/ucmlocal.mk

 # Note: A number of encodings are handled with purely algorithmic converters,
 # without any mapping tables:
 # US-ASCII, ISO 8859-1, UTF-7/8/16/32, SCSU
 
 # Listed here:
 
 # * ISO 8859-2..8,10,13,14,15,16
 #   - 8859-11 table is not included. It's rather treated as a synonym of
 #     Windows-874
 # * Windows-125[0-8]
 # * Simplified Chinese : GBK(Windows cp936), GB 18030
 #   - GB2312 table was removed and 4 aliases for GB2312 were added
 #     to GBK in convrtrs.txt to treat GB2312 as a synonym of GBK.
 #   - GB-HZ is supported now that it uses the GBK table.
 # * Traditional Chinese : Big5
 # * Japanese : SJIS (shift_jis-html), EUC-JP (euc-jp-html)
-# * Korean : Windows-949
-#  - EUC-KR table was removed. It's different from Windows-949, but
-#    in practice EUC-KR and Windows-949 are treated synonymously.
-#  - ISO-2022-KR is now supported by with a one-line change
-#    in common/ucnv2022.c and other changes in convrtrs.txt to make it
-#    use the windows-949 table.
+# * Korean : EUC-KR per the encoding spec
 # * Thai : Windows-874
 #   - TIS-620 and ISO-8859-11 are treated as synonyms of Windows-874
 #     although they're not the same.
 # * Mac encodings : MacRoman, MacCyrillic
 # * Cyrillic : KOI8-R, KOI8-U, IBM-866
 #
 # * Missing
 #  - Armenian, Georgian  : extremly rare
 #  - Mac encodings (other than Roman and Cyrillic) : extremly rare

 # Do not build EBCDIC converters.
 # ibm-37 and ibm-1047 are hardcoded in Makefile.in and
 # they're removed by modifying the file. It's also hard-coded in makedata.mak for
 # Winwodws, but we don't have to touch it because the data dll is generated out of
 # icu*.dat file generated on Linux.
