The Big5 codec provides conversion to and from the Big5 encoding.
|
|
The code was originally contributed by Ming-Che Chuang
|
|
\<mingche@cobra.ee.ntu.edu.tw\> 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 \<suzhe@turbolinux.com.cn\> \<suzhe@gnuchina.org\>
|
|
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
|
|
\<anthony@thizlinux.com\> \<foka@debian.org\> to adapt the code

\title Big5-HKSCS Text Codec
|
|
\ingroup codecs
|
|
|
|
The Big5-HKSCS codec provides conversion to and from the
|
|
Big5-HKSCS encoding.
|
|
|
|
The codec grew out of the QBig5Codec originally contributed by
|
|
Ming-Che Chuang \<mingche@cobra.ee.ntu.edu.tw\>. James Su
|
|
\<suzhe@turbolinux.com.cn\> \<suzhe@gnuchina.org\> and Anthony Fok
|
|
\<anthony@thizlinux.com\> \<foka@debian.org\> implemented HKSCS-1999
|
|
QBig5hkscsCodec for Qt-2.3.x, but it was too late in Qt development
|
|
schedule to be officially included in the Qt-2.3.x series.
|
|
|
|
Wu Yi \<wuyi@hancom.com\> ported the HKSCS-1999 QBig5hkscsCodec to
|
|
Qt-3.0.1 in March 2002.
|
|
|
|
With the advent of the new HKSCS-2001 standard, James Su
|
|
\<suzhe@turbolinux.com.cn\> \<suzhe@gnuchina.org\> generated the
|
|
Big5-HKSCS<->Unicode tables with a very space-efficient algorithm.
|
|
He generously donated his code to glibc in May 2002. Subsequently,
|
|
James has generously allowed Anthony Fok to adapt the code for
|
|
Qt-3.0.5.
|
|
|
|
Currently, the Big5-HKSCS tables are generated from the following
|
|
sources, and with the Euro character added:
|
|
\list 1
|
|
\o \l{http://www.microsoft.com/typography/unicode/950.txt}

|
\o \l{http://www.info.gov.hk/digital21/chi/hkscs/download/big5cmp.txt}
|
|
\endlist
|
|
|
|
There may be more fine-tuning to the QBig5hkscsCodec to maximize its
|
|
compatibility with the standard Big5 (2002) mapping as determined by
|
|
Li18nux Big5 Standard Subgroup. See \l{http://www.autrijus.org/xml/}
|

The GBK codec provides conversion to and from the Chinese
|
|
GB18030/GBK/GB2312 encoding.
|
|
|
|
GBK, formally the Chinese Internal Code Specification, is a commonly
|
|
used extension of GB 2312-80. Microsoft Windows uses it under the
|
|
name codepage 936.
|
|
|
|
GBK has been superseded by the new Chinese national standard
|
|
GB 18030-2000, which added a 4-byte encoding while remaining
|
|
compatible with GB2312 and GBK. The new GB 18030-2000 may be described
|
|
as a special encoding of Unicode 3.x and ISO-10646-1.
|
|
|
|
Special thanks to charset gurus Markus Scherer (IBM),
|
|
Dirk Meyer (Adobe Systems) and Ken Lunde (Adobe Systems) for publishing
|
|
an excellent GB 18030-2000 summary and specification on the Internet.

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

\ingroup codecs

|
|
The TSCII codec provides conversion to and from the Tamil TSCII
|
|
encoding.
|
|
|
|
TSCII, formally the Tamil Standard Code Information Interchange
|
|
specification, is a commonly used charset for Tamils. The
|
|
official page for the standard is at
|
|
\link http://www.tamil.net/tscii/ http://www.tamil.net/tscii/\endlink
|
|
|
|
This codec uses the mapping table found at
|
|
\link http://www.geocities.com/Athens/5180/tsciiset.html
|
|
http://www.geocities.com/Athens/5180/tsciiset.html\endlink.
|
|
Tamil uses composed Unicode which might cause some
|
|
problems if you are using Unicode fonts instead of TSCII fonts.
