The code was originally contributed by Ming-Che Chuang \ for the Big-5+ encoding, and was included in Qt with the author's permission, and the grateful thanks of the Qt team. (Note: Ming-Che's code is QPL'd, as per an mail to qt-info@nokia.com.) However, since Big-5+ was never formally approved, and was never used by anyone, the Taiwan Free Software community and the Li18nux Big5 Standard Subgroup agree that the de-facto standard Big5-ETen (zh_TW.Big5 or zh_TW.TW-Big5) be used instead. The Big5 is currently implemented as a pure subset of the Big5-HKSCS codec, so more fine-tuning is needed to make it identical to the standard Big5 mapping as determined by Li18nux-Big5. See \l{http://www.autrijus.org/xml/} for the draft Big5 (2002) standard. James Su \ \ generated the Big5-HKSCS-to-Unicode tables with a very space-efficient algorithm. He generously donated his code to glibc in May 2002. Subsequently, James has kindly allowed Anthony Fok \ \ to adapt the code for Qt. \legalese Copyright (C) 2000 Ming-Che Chuang \BR Copyright (C) 2002 James Su, Turbolinux Inc. \BR Copyright (C) 2002 Anthony Fok, ThizLinux Laboratory Ltd.

The environment variable \c 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 \link http://www.y-adagio.com/public/standards/tr_xml_jpf/toc.htm XML Japanese Profile\endlink, because it names and explains all the widely used mappings. Here are brief descriptions, written by Serika Kurusugawa: \list \o "unicode-0.9" or "unicode-0201" for Unicode style. This assumes JISX0201 for 0x00-0x7f. (0.9 is a table version of jisx02xx mapping used for Unicode 1.1.) \o "unicode-ascii" This assumes US-ASCII for 0x00-0x7f; some chars (JISX0208 0x2140 and JISX0212 0x2237) are different from Unicode 1.1 to avoid conflict. \o "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. \o "open-19970715-ascii" ("open-ascii" for convenience) for JISX0221-ASCII style. This is used when 0x5c is treated as REVERSE SOLIDUS. \o "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. \o "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. \endlist 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 \c UNICODEMAP_JP to \c {unicode-0.9, nec-vdc}. (You will probably need to quote that in a shell command.)
