Addition of thirteen linguistic educational characters

This document proposes fourteen characters used in the Japanese educational field, anddiscusses the rationale for their inclusion.
A new Japanese Industrial Standard, JIS X0213 is being developed in Japan, and it will be
published 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.
The proposed characters are mainly used in the phonetic field. They also appear in theschool text books. Nine Latin characters are pre-composed with accent mark. Two symbols comefrom the official IPA reference. UCS’s IPA repertoire is completed by including these characters.
Rest two are arrows that are often used to denote the intonation of the sentence.
The characters proposed to be added here are given below, with proposed code positions. The
proposal summary form is appended thereafter.
