Information technology -- Character code structure and extension techniques

Abstract

Cancels and replaces the third edition (1986). Specifies the structure of 8-bit codes and 7-bit codes which provide for the coding of character sets. The codes specified here are designed to be used for data that is processed sequentially in a forward direction. Use of these codes in strings of data which are processed in some other way, or which are included in data formatted for fixed-length record processing, may have undesirable results or may require additional special treatment to ensure correct interpretation.
