What is ISO/IEC 14651 about?
ISO/IEC 14651 is an International Standard on programming languages, their environments, and system software interfaces that build networks for a company, safeguard data and information, creating and administer databases.
ISO/IEC 14651 is applicable to two-character strings to determine their collating order in a sorted list on the comparison method. This method uses collation tables derived either from the Common template table defined in this ISO/IEC 14651 or from one of its tailorings.
NOTE 1: This Common Template Table is to be modified to suit the needs of a local environment. The main worldwide benefit is that, for other scripts, often no modification is required, and the order will remain as consistent as possible and predictable from an international point of view.
NOTE 2: The character repertoire used in this document is equivalent to that of the Unicode Standard version 13.0.
ISO/IEC 14651 does not mandate the following:
- A specific comparison method: any equivalent method giving the same results is acceptable
- A specific format for describing or tailoring tables in a given implementation
- Specific symbols to be used by implementations, except for the name of the Common Template Table
- A context-dependent ordering
- Any particular preparation of character strings prior to comparison
Who is ISO/IEC 14651 for?
BS ISO/IEC 14651:2020 on information technology is relevant to:
- IT industry
- Software programmers
- Developers
- Data analytics companies
- Data processing service providers
Why should you use ISO/IEC 14651?
A string is a data type used in programs, such as an integer and floating-point unit, but is used to represent text rather than numbers.
ISO/IEC 14651 specifies the comparison method includes a procedure for solving systems of independent equations that starts by rewriting each equation with the same variable as the subject.
ISO/IEC 14651 describes a method to order text data independently of context which provides the most efficient computation of terms used for deriving valuable information.
ISO/IEC 14651 is beneficial for data processors as it provides ease of use, internationalization support, and compatibility with existing interfaces.
What’s changed since the last update?
BS ISO/IEC 14651:2020 replaces the fifth edition (ISO/IEC 14651:2019), which has been
technically revised. The main changes compared to the previous edition are as follows:
- Ordering data has been added for the new characters standardized in the sixth edition of ISO/IEC 10646 (2020)
- The content of 6.2.2 has been revised for more completeness
- The weights of character U+A9B5 (JAVANESE VOWEL SIGN TOLONG) have been changed, as the latter is considered a variant of character U+A9B4 (JAVANESE VOWEL SIGN TARUNG). This needed to be fixed
