## Detailed Description

The QJpUnicodeConv class provides implementation support for QJisCodec, QSjisCodec, and QEucJpCodec.

You should not need to use this class directly. If you do, keep in mind that the function names will change in Qt 3.0: Every function name will get a lower-case first letter: Jisx0212ToUnicode becomes jisx0212ToUnicode, and so on. We apologize for the upheaval.

The environment variable `UNICODEMAP_JP` can be used to fine-tune how QJpUnicodeConv, QEucJpCodec, QJisCodec and QSjisCodec do their work. The mapping names are as for the Japanese XML working group's XML Japanese Profile, as it names and explains all the widely used mappings. Here are brief descriptions, written by Serika Kurusugawa:

- "unicode-0.9" or "unicode-0201" for Unicode style. This assume JISX0201 for 0x00-0x7f. (0.9 is a table version of jisx02xx mapping used for Uniocde spec version 1.1)
- "unicode-ascii" This assume US-ASCII for 0x00-0x7f, and some chars (JISX0208 0x2140 and JISX0212 0x2237) are different from Unicode 1.1 to avoid conflict.
- "open-19970715-0201" ("open-0201" for convenience) or "jisx0221-1995" for JISX0221-JISX0201 style. JIS X 0221 is JIS version of Unicode, but a few chars (0x5c, 0x7e, 0x2140, 0x216f, 0x2131) are different from Unicode 1.1. This is used when 0x5c is treated as YEN SIGN.
- "open-19970715-ascii" ("open-ascii" for convenience) for JISX0221-ASCII style. This is used when 0x5c is treated as REVERSE SOLIDUS.
- "open-19970715-ms" ("open-ms" for convenience) or "cp932" for Microsoft Windows style. Windows Code Page 932. Some chars (0x2140, 0x2141, 0x2142, 0x215d, 0x2171, 0x2172) are different from Unicode 1.1.
- "jdk1.1.7" for Sun's JDK style Same as Unicode 1.1, except that JIS 0x2140 is mapped to UFF3C. Either ASCII or JISX0201 can be used for 0x00-0x7f.

In addition, QJpUnicodeConv supports some extensions: "nec-vdc", "ibm-vdc" or "udc".

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 the shell command.)
