Code page 928, the double byte component, included 9356 characters as double-byte sequences starting with 0x81 through 0xAC and 0xF0 through 0xFA. It was documented in 1992 and superseded in 1993 by Code page 1380, encoding the same characters in a different layout. Documentation for Code page 1380 (the document C-H 3-3220-130 1993-11) is provided online by IBM, whereas IBM do not similarly provide the documentation for the older Code page 928 (the document C-H 3-3220-130 1992-11) and suggest contacting them for more information.
IBM code page 936 should not be confused with the identically numbered Windows code page, which is a variant of the GBK encoding and is called Code page 1386 by IBM. International Components for Unicode does not include an IBM-936 codec, and uses the Windows code page for the "cp936" label.
