.SH NAME
QGb18030Codec \- Conversion to and from the Chinese GB18030/GBK/GB2312 encoding
.SH SYNOPSIS
All the functions in this class are reentrant when TQt is built with thread support.</p>
.PP
\fC#include <ntqgb18030codec.h>\fR
.PP
Inherits QTextCodec.
.PP
Inherited by QGbkCodec and QGb2312Codec.
.PP
.SH DESCRIPTION
The QGb18030Codec class provides conversion to and from the Chinese GB18030/GBK/GB2312 encoding.
.PP
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.
.PP
GBK has been superceded by the new Chinese national standard GB 18030-2000, which added a 4-byte encoding while remaining compatible with GB2312 and GBK.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.
.PP
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. Some must-read documents are:

The GBK codec was contributed to TQt by Justin Yu <justiny@turbolinux.com.cn> and Sean Chen <seanc@turbolinux.com.cn>. They may also be reached at Yu Mingjian <yumj@sun.ihep.ac.cn>, <yumingjian@china.com> Chen Xiangyang <chenxy@sun.ihep.ac.cn>
.PP
The GB18030 codec TQt functions were contributed to TQt by James Su <suzhe@gnuchina.org>, <suzhe@turbolinux.com.cn> who pioneered much of GB18030 development on GNU/Linux systems.
.PP
The GB18030 codec was contributed to TQt 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. A copy of the source Perl script is available at:
