ISO/IEC 10367:1991

Overview

ISO/IEC 10367:1991 - Information technology - Standardized coded graphic character sets for use in 8-bit codes - defines a standardized collection of coded graphic character sets for 8-bit code environments. Developed by ISO and IEC, this international standard specifies a unique G0 set and multiple supplementary G1, G2, and G3 sets for use in implementations of ISO/IEC 4873. By providing standardized character sets, including Latin, Cyrillic, Greek, Arabic, and Hebrew scripts, ISO/IEC 10367 ensures consistent representation and interchange of graphic characters across global information technology and data processing systems.

Key Topics

• Standardized 8-bit Coded Character Sets: Defines the structure and elements of 8-bit graphic character sets, facilitating multi-language data representation and exchange.
• Supplementary Sets for Multiple Languages: Specifies several Latin alphabet supplementary sets and additional sets for Cyrillic, Arabic, Greek, and Hebrew scripts, ensuring coverage for diverse languages.
• Application Alignment with ISO/IEC 4873: The character sets are designed for use within the multi-level code extension structure of ISO/IEC 4873, supporting up to four graphic sets in parallel.
• Character Naming and Notation: Establishes unique, unambiguous names, conventions, and symbols for each character, supporting clear identification.
• Conformance Requirements: Outlines the requirements for information interchange and device compatibility, ensuring consistent use in both originating and receiving equipment.
• Code Table Structure: Details the layout of 8-bit code tables, with positions, columns, and rows mapped to specific character bit combinations.

Applications

ISO/IEC 10367:1991 plays a crucial role in standardizing character encoding for a range of practical applications:

• Data and Text Processing Systems: Ensures reliable, standardized representation of characters in office automation, desktop publishing, and general computing environments.
• Multilingual Information Interchange: Facilitates the seamless exchange of textual data between systems using different scripts or character sets, vital for international communication and documents.
• Software and Hardware Compatibility: Enables software applications, operating systems, and devices (e.g., printers, terminals, and displays) to process and correctly render a broad array of languages and scripts.
• Globalization of IT Solutions: Supports global markets by providing a consistent foundation for multi-language support in information technology products and services.
• Legacy and Cross-Platform Systems: Assists in integration and interoperability between legacy systems and modern platforms using different 8-bit coded character specifications.

Related Standards

ISO/IEC 10367:1991 is closely interconnected with several other key international standards in character coding and information interchange:

• ISO/IEC 4873: Defines the general structure and rules for the implementation of 8-bit codes for information interchange, into which ISO/IEC 10367 character sets are integrated.
• ISO 2022: Provides code extension techniques for 7-bit and 8-bit coded character sets, forming a basis for multi-set encoding strategies used by ISO/IEC 10367.
• ISO/IEC 6429: Specifies control functions for character sets in information technology, relevant for managing control code assignments within 8-bit codes.
• ISO/IEC 6937: Focuses on multiscript text communication using the Latin alphabet and non-spacing diacritical marks.
• ISO/IEC 8859: Covers a comprehensive suite of 8-bit single-byte coded graphic character sets for various scripts and languages.
• ISO 2375: International Register of Coded Character Sets to Be Used with Escape Sequences, supporting registration and identification of character sets referenced in ISO/IEC 10367.

By leveraging ISO/IEC 10367:1991, organizations and technology providers benefit from robust, internationally recognized character set specifications, ensuring interoperability, language support, and data integrity in multilingual 8-bit code environments.
