ISO 2022-JP (JIS) Text Codec

The JIS codec provides conversion to and from ISO 2022-JP.

The environment variable UNICODEMAP_JP can be used to fine-tune the JIS, Shift-JIS, and EUC-JP codecs. The mapping names are as for the Japanese XML working group's XML Japanese Profile, because it names and explains all the widely used mappings. Here are brief descriptions, written by Serika Kurusugawa:

In addition, the extensions "nec-vdc", "ibm-vdc" and "udc" are supported.

For example, if you want to use Unicode style conversion but with NEC's extension, set UNICODEMAP_JP to unicode-0.9, nec-vdc. (You will probably need to quote that in a shell command.)
