• Japanese standard character set JIS X0208 has been widely utilized in Japanese computer systems for over ten years. This character set has 6877 characters including 6353 kanji or Chinese characters, and seems to be nearly sufficient for daily use of Japanese text processing. However, the total number of kanji characters is more than fifty thousand, and the missing character problem is inevitable for some application fields. In this paper, problems around character codes are discussed from the following four view points: Japanese writing systems, script of Japanese writing system, inter-change character set, and internal codes of operating systems. At the first, Japanese writing system is briefly introduced, and kanji script and variant forms are discussed. Then, topics around the JIS X0208 and the new standard character set are introduced, and the internal code design of JEF, shift-JIS, UNIX EUC-JAE, and TRON TAD are described. Problems are mainly in two points. The vast number of kanji characters and the ambiguity of the graphic forms causes problems in the character set controloperation. And the increasement of character sets may introduce difficulties into the internal code designs. For the resolution of these problems, efforts on both the linguistic field and computer science field will be required.
