Nowadays, Code page 932 (IBM) is a topic that has gained great relevance in society. From its origin to the present, Code page 932 (IBM) has had a significant impact on people's lives. Whether on a personal, social, political or economic level, Code page 932 (IBM) has generated debates, controversies and changes in different areas. Throughout history, Code page 932 (IBM) has been the object of study, reflection and analysis by experts and academics. In this article, we will explore the importance of Code page 932 (IBM) and its influence on society today, as well as its possible implications for the future.
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. Code page 301 is designed to encode the same repertoire as IBM Japanese DBCS-Host.
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.
