IBM code page 932 (abbreviated as IBM-932 or ambiguously as CP932) is one of IBM's extensions of Shift JIS. The coded character sets are JIS X 0201:1976, JIS X 0208:1983, IBM extensions and IBM extensions for IBM 1880 UDC. It is the combination of the single-byte Code page 897 and the double-byte Code page 301.
IBM-932 resembles IBM-943. One difference is that IBM-932 encodes the JIS X 0208:1983 characters but preserves the 1978 ordering, whereas IBM-943 uses the 1983 ordering (i.e. the character variant swaps made in JIS X 0208:1983). Another difference is that IBM-932 does not incorporate the NEC selected extensions, which IBM-943 includes for Microsoft compatibility.
IBM-942 includes the same double-byte codes as IBM-932 (those from Code page 301) but includes additional single-byte extensions. International Components for Unicode treats "ibm-932" and "ibm-942" as aliases for the same decoder.
IBM-932 contains 7-bit ISO 646 codes, and Japanese characters are indicated by the high bit of the first byte being set to 1. Some code points in this page require a second byte, so characters use either 8 or 16 bits for encoding.
Code page 897 is IBM's implementation of the 8-bit form of JIS X 0201. It includes several additional graphical characters in the C0 control characters area, and the code points in question may be used as control characters or graphical characters depending on the context, similarly in concept to OEM-US, but with different graphical characters. The C0 rows are shown below.Amongst IBM's code pages, it accompanies code page 895, which encodes the ISO 646 set of JIS X 0201, and code page 896 (half-width katakana), which encodes the Kana set (upper half) of JIS X 0201 with extensions. When combined with the double-byte code page 301, it makes up the two code-sets of IBM code page 932 (IBM PC Japan MIX). When combined with the double-byte code page 941, it makes up code page 943 (equivalent to Windows-932, although Microsoft uses ASCII mappings for 0x00 though 0x7F). When combined with the double-byte code page 1393, it makes up code page 1394.Code page 932
