ISO 15924
ISO 15924 is a standard published by the International Organization for Standardization , which denotes abbreviations for writing systems. Each writing system has both a four-character abbreviation and a numerical code.
These abbreviations are required, for example, to assign characters that have been merged in Unicode (such as Fraktur or Chinese characters ) to a font and to give them a different appearance by selecting a font. For example, a distinction can be made in HTML and XML between German in Latin script ( de-Latn) and German in Fraktur ( de-Latf). It is also z. B. necessary for Chinese characters in order to distinguish between simplified and traditional characters, with Hansand Hantfor simplified or traditional Chinese characters.
administration
ISO 15924 is administered by the Unicode Consortium . In 2004 Michael Everson was named as registrar.
Code system
The numerical values assigned in addition to the mnemonic four-letter codes are in a tradition of comparable ISO coding systems and enable people who cannot or hardly read the Latin script to use the “Arabic” numerals that are used in many more writing systems instead work.
