Code page 949 (IBM)

April 13, 2024

IBM code page 949 (IBM-949) is a character encoding which has been used by IBM to represent Korean language text on computers. It is a variable-width encoding which represents the characters from the Wansung code defined by the South Korean standard KS X 1001 in a format compatible with EUC-KR, but adds IBM extensions for additional hanja, additional precomposed Hangul syllables, and user-defined characters.

Giving values in hexadecimal, bytes 0x00 through 0x7F are used for single byte KS X 1003 (ISO 646:KR) characters, a similar set to ASCII but with a won sign rather than a backslash. Bytes 0x80 through 0x84 are used for IBM single byte extension characters. Lead bytes 0x8F through 0xA0 are used for IBM double byte extension characters. Lead bytes 0xA1 through 0xFE are used for Wansung code (KS X 1001 characters in EUC-KR form, double byte), but with some unused space opened up for user-defined use.

Although both are sometimes named "cp949", IBM-949 is different from Windows code page 949 (IBM-1363), which is Microsoft's Unified Hangul Code, a different extension of EUC-KR. It should also not be confused with IBM's implementation of plain EUC-KR (IBM-970). Code page 949 in OS/2 is the IBM code page; however, a third-party patch exists to change this.[1]

Terminology and encoding labelling edit

Both IBM-949 and Unified Hangul Code (Windows-949) are known as "code page 949" (or "cp949") although they share only the EUC-KR subset in common. Neither has a standardised IANA-registered label to identify it. Although UHC is included in the WHATWG Encoding Standard,[2] with labels including "windows-949",[3] IBM-949 is not. IBM-949 therefore is not permitted in HTML5.

Although the meaning of the label "ibm-949" (and conversely "windows-949" and "ms949") is unambiguous where these labels are supported, the interpretation of the encoding labels "949" and "cp949" consequently varies between implementations. For example, International Components for Unicode uses "cp949", "949", "ibm-949" and "x-IBM949" to refer to IBM-949,[4] and additionally the labels "cp949c", "ibm-949c" and "x-IBM949C" to refer to an variant which uses unmodified ASCII mappings for 0x20–7E (resulting in duplicate mappings for the backslash),[5] while (of the labels incorporating the code page number 949) only "ms949" and "windows-949" are assigned to UHC.[6] This is in contrast to Python, which recognises both "cp949" and "949" (in addition to the more explicit "ms949" and "uhc", but not "windows-949") as labels for UHC, and does not include an IBM-949 codec.[7] The code page 949 used by Korean language versions of OS/2 is the IBM code page; to add support for the entire Unicode set of Korean syllables, a third-party patch exists to replace it with the Microsoft code page.[1]

IBM-949 is a variable width encoding defined as the combination of two fixed-width code pages, the single-byte Code page 1088 and the double-byte Code page 951.[8][9][10]

History edit

A version of Code page 951 (a DBCS-PC, i.e. double-byte non-EUC non-EBCDIC, code), the double-byte component for IBM-949, is defined in the September 1992 revision of IBM Corporate Specification C-H 3-3220-125, along with Code page 834 (a DBCS-Host, i.e. double-byte EBCDIC, code), which is the double byte component of Code page 933.[11] This version of Code page 949/951 considered the entire lead byte range 0x8F–A0 to be a user-defined region, and included only standard Wansung assignments and user-defined areas, thus not including some characters which Code page 933/834 included.[11] Some later versions, such as that implemented by International Components for Unicode (ICU), shrink the user-defined region to include these characters as extensions.[12]

The earlier October 1989 revision of C-H 3-3220-125 had instead defined Code page 926 as its DBCS-PC code, which encoded the same characters as IBM-834 in a layout differing from both IBM-951 and IBM-834, which had a different lead byte range and was not an EUC-KR extension.[11] IBM-926 was combined with Code page 891 or Code page 1040 (respectively 8-bit N-byte Hangul Code and an extension thereof; compare how Shift JIS extends 8-bit JIS X 0201) to form IBM-934 or IBM-944 respectively.[13][14]

Code page 944/926 are now deprecated in favour of IBM-949. The 1992 revision designates code page 926 as "restricted" ("limited to the particular environment for which [it is] registered") and does not give its chart or mappings from the other code pages,[11] and CCSID 944 is categorised as "coexistence and migration"[14] (contrast "interoperable" for CCSID 949).[8] International Components for Unicode includes Unicode mappings for IBM-949[4][12] and IBM-933, but its IBM-944 mapping was removed in 2001.[15]

Double byte codes edit

Lead bytes 0x8F–99, 0xC9, 0xFE (user-defined ranges) edit

IBM-949 is designed to support a maximum of 1880 UDC (user-defined characters),[8] including the user-defined rows (lead bytes 0xC9 and 0xFE) of the Wansung plane, and ranges outside the Wansung plane. In this version, the lead bytes 0x8F–A0 contain a maximum of 1692 UDC, and lead bytes 0xC9 and 0xFE contain a maximum of 94 each (i.e. with trail bytes 0xA1–FE).[11] However, when the extensions to support the entire double-byte repertoire of IBM-933 are implemented, they use lead bytes 0x9A–A0, resulting in a smaller maximum number of characters left for user definition.[4][12]

When mapped to Unicode, 0xC9A1–C9FE (between the syllable and hanja ranges) are mapped to the Unicode Private Use Area code points U+E000–E05D, while 0xFEA1–FEFE (between the end of the hanja range and the end of the plane) are mapped to U+E05E–E0BB. Outside the Wansung plane, 0x8FA0–9AA5 (where the second byte is in the range 0xA1–FE) are mapped to the Private Use Area code points U+E0BC–E4CA.[4] The last of these ranges cuts into the start of the 0x9A row (shown below).

Collectively these private use ranges cover the code points U+E000–E4CA, allowing 1227 UDC to be mapped from IBM-949 to Unicode.[12] The separate private use area range U+F843–F86E is used by IBM to map some characters within the extended hanja range.[12] This follows early recommendations from the Unicode Consortium that corporate characters be allocated from U+F8FF downward and user-defined characters be allocated from U+E000 upward,[18] and is part of a larger corporate private use area scheme which is defined internally by IBM, and uses the range U+F83D–F8FF.[19][20]

Lead bytes 0x9A–9D (extended symbols and hanja) edit

According to the 1992 specification, this entire range is user-defined.[11] As implemented in the codec contributed to ICU by IBM, however, 0x9AA1 through 0x9AA5 are the end of the user-defined range. The remainder of this range includes some non-Hangul characters included in Code page 933 but not in Wansung code. 0x9AA6 through 0x9AAB contain miscellaneous technical or mathematical symbols. The remainder contains hanja additional to those included in KS X 1001, although some are mapped by IBM to the Private Use Area.[12]

Lead bytes 0x9E–A0 (extended hanja and hangul syllables) edit

According to the 1992 specification, this entire range is user-defined.[11] As implemented in the codec contributed to ICU by IBM, 0x9EA1 through 0x9EAC contain the remainder of the extended hanja. The rest of the range contains a few additional Hangul syllables which are not available in pre-composed form in pure EUC-KR. Unlike Unified Hangul Code, this is insufficient to support all non-partial Johab syllables absent in Wansung code.[12]

Significant amongst these are 뢔 (0x9EFC), 쌰 (0x9FE6), 쎼 (0x9FED), 쓔 (0x9FF3) and 쬬 (0xA0C1), which correspond to the beginnings of the standard Wansung characters 뢨, 썅, 쏀, 쓩, and 쭁 respectively, when partly entered in an input method editor.

Footnotes edit

  1. ^ This is not included for IPA support. Rather, in Code page 933, SO 0x4160 is a not-equals sign displayed with a slash, while IBM-933 SO 0x418D is one displayed with a backslash (i.e. =⃥).[11] Although it is IBM-933 SO 0x4160 which is mapped to the usual not-equals GCGID SA540080 (fullwidth of SA540000), it is IBM-933 SO 0x418D which is mapped to EUC-KR and IBM-949 0xA1C1,[11] due to the reference glyph for the not-equals sign in KS C 5601-1987 also showing it with a backslash.[23] Hence, U+2260, which is mapped to EUC-KR and therefore IBM-949 0xA1C1, is mapped to IBM-933 SO 0x418D, leaving IBM-933 SO 0x4160 (and therefore IBM-949 0x9AA6) to be mapped to the visually similar character at U+01C2.[24]
  2. ^ The mapping from IBM is U+5231 刱, but the glyph in the IBM document C-H 3-3220-125 1992-09 is closer to U+5259 剙 (host code 62D5).[11]

the more explicit ms949 and uhc but not windows 949 as labels for UHC and does not include an IBM 949 codec 7 The code page 949 used by Korean language versions of OS 2 is the IBM code page to add support for the entire Unicode set of Korean syllables a third party patch exists to replace it with the Microsoft code page 1 IBM 949 is a variable width encoding defined as the combination of two fixed width code pages the single byte Code page 1088 and the double byte Code page 951 8 9 10 History editA version of Code page 951 a DBCS PC i e double byte non EUC non EBCDIC code the double byte component for IBM 949 is defined in the September 1992 revision of IBM Corporate Specification C H 3 3220 125 along with Code page 834 a DBCS Host i e double byte EBCDIC code which is the double byte component of Code page 933 11 This version of Code page 949 951 considered the entire lead byte range 0x8F A0 to be a user defined region and included only standard Wansung assignments and user defined areas thus not including some characters which Code page 933 834 included 11 Some later versions such as that implemented by International Components for Unicode ICU shrink the user defined region to include these characters as extensions 12 IBM code pages 934 and 944Language s KoreanExtendsN byte Hangul CodeTransforms EncodesCode page 933Succeeded byIBM code page 949vteThe earlier October 1989 revision of C H 3 3220 125 had instead defined Code page 926 as its DBCS PC code which encoded the same characters as IBM 834 in a layout differing from both IBM 951 and IBM 834 which had a different lead byte range and was not an EUC KR extension 11 IBM 926 was combined with Code page 891 or Code page 1040 respectively 8 bit N byte Hangul Code and an extension thereof compare how Shift JIS extends 8 bit JIS X 0201 to form IBM 934 or IBM 944 respectively 13 14 Code page 944 926 are now deprecated in favour of IBM 949 The 1992 revision designates code page 926 as restricted limited to the particular environment for which it is registered and does not give its chart or mappings from the other code pages 11 and CCSID 944 is categorised as coexistence and migration 14 contrast interoperable for CCSID 949 8 International Components for Unicode includes Unicode mappings for IBM 949 4 12 and IBM 933 but its IBM 944 mapping was removed in 2001 15 Single byte codes

user defined characters 8 including the user defined rows lead bytes 0xC9 and 0xFE of the Wansung plane and ranges outside the Wansung plane In this version the lead bytes 0x8F A0 contain a maximum of 1692 UDC and lead bytes 0xC9 and 0xFE contain a maximum of 94 each i e with trail bytes 0xA1 FE 11 However when the extensions to support the entire double byte repertoire of IBM 933 are implemented they use lead bytes 0x9A A0 resulting in a smaller maximum number of characters left for user definition 4 12 When mapped to Unicode 0xC9A1 C9FE between the syllable and hanja ranges are mapped to the Unicode Private Use Area code points U E000 E05D while 0xFEA1 FEFE between the end of the hanja range and the end of the plane are mapped to U E05E E0BB Outside the Wansung plane 0x8FA0 9AA5 where the second byte is in the range 0xA1 FE are mapped to the Private Use Area code points U E0BC E4CA 4 The last of these ranges cuts into the start of the 0x9A row shown below Collectively these private use ranges cover the code points U E000 E4CA allowing 1227 UDC to be mapped from IBM 949 to Unicode 12 The separate private use area range U F843 F86E is used by IBM to map some characters within the extended hanja range 12 This follows early recommendations from the Unicode Consortium that corporate characters be allocated from U F8FF downward and user defined characters be allocated from U E000 upward 18 and is part of a larger corporate private use area scheme which is defined internally by IBM and uses the range U F83D F8FF 19 20 Lead bytes 0x9A 9D extended symbols and hanja edit According to the 1992 specification this entire range is user defined 11 As implemented in the codec contributed to ICU by IBM however 0x9AA1 through 0x9AA5 are the end of the user defined range The remainder of this range includes some non Hangul characters included in Code page 933 but not in Wansung code 0x9AA6 through 0x9AAB contain miscellaneous technical or mathematical symbols The remainder contains hanja additional to those included in KS X 1001 although some are mapped by IBM to the Private Use Area 12 IBM code page 949 extended symbols and hanja 12 22 0 1 2 3 4 5 6 7 8 9 A B C D E F9AAx ǂ a K
