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.<ref name="ch3320125-1992"/> IBM-926 was combined with [[Code page 891]] or [[Code page 1040]] (respectively 8-bit [[KS X 1001#1974|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.<ref name="ccsid934">{{cite web |archive-url=https://web.archive.org/web/20141202014525/http://www-01.ibm.com/software/globalization/ccsid/ccsid934.html |archive-date=2014-12-02 |url=http://www-01.ibm.com/software/globalization/ccsid/ccsid934.html |title=Coded character set identifiers: CCSID 934 |work=IBM Globalization |publisher=[[IBM]] |url-status=dead}}</ref><ref name="ccsid944">{{cite web |archive-url=https://web.archive.org/web/20141201233858/http://www-01.ibm.com/software/globalization/ccsid/ccsid944.html |archive-date=2014-12-01 |url=http://www-01.ibm.com/software/globalization/ccsid/ccsid944.html |title=Coded character set identifiers: CCSID 944 |work=IBM Globalization |publisher=[[IBM]] |url-status=dead}}</ref>
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,<ref name="ch3320125-1992"/> and CCSID 944 is categorised as "coexistence and migration"<ref name="ccsid944"/> (contrast "interoperable" for CCSID 949).<ref name="ccsid949"/> International Components for Unicode includes [[Unicode]] mappings for IBM-949<ref name="icu"/><ref name="ucm"/> and IBM-933, but its IBM-944 mapping was removed in 2001.<ref>{{cite web |url=https://github.com/unicode-org/icu/commit/4b5d175d834a24a0ec08fbbf1d2e20385ef78af1#diff-8403419f92b19da4ade420a7d6a94b603a7d0bd5f62d672eee888a62f50a2886 |title=ICU-1281 Remove unwanted ucmfiles |work=[[International Components for Unicode]] |date=2001-11-01 |first=Ram |last=Viswanadha}}</ref>
