This article is about IBM's Code Page 932. For the Microsoft Windows code page 932, see Code page 932 (Microsoft Windows).

IBM code page 932 (abbreviated as IBM-932[1] 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,[1] IBM extensions and IBM extensions for IBM 1880 UDC. It is a combination of the single-byte Code page 897 and the double-byte Code page 301.[2]

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 incorporates the character variant swaps made in JIS X 0208:1983.[1] Another difference is that IBM-932 does not incorporate the NEC selected extensions which IBM-943 includes.[1] IBM-932 also resembles IBM-942, which includes the same double-byte codes as IBM-932 (those from Code page 301) but includes additional single-byte extensions.

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.
