|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
<p> The QGb18030Codec class provides conversion to and from the Chinese
|
||
|
|
GB18030/GBK/GB2312 encoding.
|
||
|
|
<p>
|
||
|
|
<p> 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.
|
||
|
|
<p> GBK has been superceded by the new Chinese national standard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.
|
||
|
|
<p> 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.

<p> The GBK codec was contributed to Qt by
|
||
|
|
Justin Yu <justiny@turbolinux.com.cn> and
|
||
|
|
Sean Chen <seanc@turbolinux.com.cn>. They may also be reached at

|

|
|
<p> The GB18030 codec Qt functions were contributed to Qt by
|
||
|
|
James Su <suzhe@gnuchina.org>, <suzhe@turbolinux.com.cn>
|
||
|
|
who pioneered much of GB18030 development on GNU/Linux systems.
|
||
|
|
<p> The GB18030 codec was contributed to Qt by
|
||
|
|
Anthony Fok <anthony@thizlinux.com>, <foka@debian.org>
|
||
|
|
using a Perl script to generate C++ tables from gb-18030-2000.xml
|
||
|
|
while merging contributions from James Su, Justin Yu and Sean Chen.
|
||
|
|
