This document proposes forty eight characters used in Japan, and discusses the rationale fortheir inclusion.
A new Japanese Industrial Standard, JIS X0213 is being developed in Japan, and it will bepublished by the end of this year. The new standard will include all characters in this proposal,
so the adoption of them is very important in the view to keep upward compatibility with theJapanese products.
Twenty extended KATAKANAs are used to describe the Language of AINU, Japaneseaborigine. Though AINU does not have their own writing system, KATAKANA characters arecommonly used to describe them. Characters in this proposal are supplied to the KATAKANA
repertoire, and commonly used in the publications such as books and newspapers.
Two small HIRAGANA letters are adopted for compatibility. They are usually used as
KATAKANA characters and small KATAKANAs are already coded. But in many application
programs such as input system requires HIRAGANA characters correspond to them.
Five extended HIRAGANA letters and Five extended KATAKANA letters are mainly used todescribe precise pronunciation of Japanese. Usually Japanese pronunciation is normalized as
fifty syllabics, but there are more syllabics for the precise pronunciation. They are referred as
BIDAKUON. To describe such kind of syllabics, HIRAGANA characters in this proposal aresupplied to the HIRAGANA repertoire. Most major broadcasting stations in Japan such as NHK,takes this system, and there are some user communities.
Rest sixteen characters are used for Japanese publications.
The characters proposed to be added here are given below, with proposed code positions. The
proposal summary form is appended thereafter.
