Volume 1 of the Association of Radio Industries and Businesses (ARIB) STD-B24 standard for Broadcast Markup Language[2] specifies, amongst other details, a character encoding for use in Japanese-language broadcasting. It was introduced on 1999-10-26.[2] The latest revision is version 6.3 as of 2016-07-06.

It includes a number of ARIB extended characters (ARIB外字, ARIB gaiji) not found in the base standards (JIS X 0208 and JIS X 0201). It was the source standard for many symbol characters which were added to Unicode, including portions of the Miscellaneous Symbols, Enclosed Alphanumeric Supplement and Enclosed Ideographic Supplement blocks.[3] Its contributions partially overlap the Unicode emoji, but were added a year earlier, in Unicode 5.2.[4]

Fascicle 1 of the ARIB STD-B62 standard, published in 2014, defines Unicode mappings for a selection of the B24 extended characters (excluding, for example, those duplicated by JIS X 0213), as well as a few extended Kanji.[5] It also includes a mapping of utilised characters outside the Basic Multilingual Plane to the BMP's private use area.
