Chapter 9: Information Processing Techniques

I have written a tool, called JChar, that generates these problematic character sets (and

nonproblematic ones, too!). Listings of these noncoded Japanese character set standards,

as generated by JChar, are in Appendix J.

e JChar tool has many features and options that you will nd useful at some time or

another—the main ones are as follows:

Supports the JIS X 0208:1997, ASCII/JIS-Roman, half-width katakana, Jōyō Kanji, •

Gakushū Kanji, and Jinmei-yō Kanji character sets

Outputs data in ISO-2022-JP, Shi-JIS, or EUC-JP encoding•

Wraps output lines at • n columns

Can suppress header information•

Algorithms used in this tool are primarily loops (for the coded character sets) and data

structures (for the noncoded character sets). Encoding range bounds are used, though, to

generate the whole character encoding space, and not just the code positions that contain

characters. For example, when choosing to generate the JIS X 0208:1997 list, it does not

generate 6,879 code positions, but does 8,836 code positions, which is what you get from

a complete 94×94 matrix.

Here is this tool’s help page:
