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. Its contributions partially overlap the Unicode emoji, but were added a year earlier, in Unicode 5.2.
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. It also includes a mapping of utilised characters outside the Basic Multilingual Plane to the BMP's private use area.
