Encoding formats
  • ARIB STB-B24 encoding (ISO 2022 based)
  • Shift JIS (ARIB variant)[1]

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.

Sets and codes[edit]

The ARIB STD B24 standard defines multiple character sets and a method of switching between them. These include a Kanji set (an extension of JIS X 0208), an Alphanumeric set, a Hiragana set, Katakana sets of two distinct layouts and four mosaic sets.[6] The sets are selected using ISO 2022 mechanisms for 94-sets, using the following codes (proportional sets use the same layout as the corresponding non-proportional ones):[7]

Set Type Code (column/line) Code (hexadecimal) Code (ASCII character) Comments
Kanji 2-byte 4/2 42 B The escape code B used for the ARIB Kanji set[7] is used for the 1983 version of JIS C 6226 (JIS X 0208, of which the ARIB Kanji set is an extension) in ISO-2022-JP.[8][9]
Alphanumeric 1-byte 4/10 4A J JIS_C6220-ro (ISO646-JP, JIS X 0201 Roman set). Similar to ASCII, with two assignments differing. Escape code J matches usage in ISO-2022-JP.[9]
Proportional alphanumeric 1-byte 3/6 36 6
Hiragana 1-byte 3/0 30 0 Hiragana themselves follow the same layout as row 4 of JIS X 0208, but without a lead byte. Also adds several additional assignments for punctuation.
Proportional Hiragana 1-byte 3/7 37 7
Katakana 1-byte 3/1 31 1 Katakana themselves follow the same layout as row 5 of JIS X 0208, but without a lead byte. Also adds several additional assignments for punctuation.
Proportional Katakana 1-byte 3/8 38 8
JIS X 0201 Katakana 1-byte 4/9 49 I JIS_C6220-jp (JIS X 0201 Kana set). Escape code matches usage in ISO-2022-JP-3.
Mosaic A 1-byte 3/2 32 2 Pseudographics
Mosaic B 1-byte 3/3 33 3
Mosaic C 1-byte 3/4 34 4 Non-spacing pseudographics
Mosaic D 1-byte 3/5 35 5

Code charts[edit]

Kanji (double-byte) set[edit]

This is a double-byte character set extending JIS X 0208.

Lead byte[edit]

The encoding bytes correspond to the row or cell number plus 0x20, or 32 in decimal (see below). Hence, the code set starting with 0x21 has a row number of 1, and its cell 1 has a continuation byte of 0x21 (or 33), and so forth. Most of the code corresponds to JIS X 0208.

Character sets 0x21-0x74 (row numbers 1-84: punctuation, alphabets, numbers, Kana, Kanji)[edit]

Character set 0x7A (row number 90, traffic symbols)[edit]

Characters 90-45 through 90-63 and 90-66 through 90-84 (shown below shaded) are listed in the B24 standard only in table 7-10 (the list of extension characters), and are also the only characters in rows 90 through 91 which are not transport-related symbols; this is noted in the B24 standard in an endnote to table 7-10.[10] The remainder of the extensions are listed in both table 7-4 (the double-byte code chart) and table 7-10.[10]
