< p > The TQGb18030Codec class provides conversion to and from the Chinese
GB18030/GBK/GB2312 encoding.

< 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 GBK has been superceded by the new Chinese national standard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 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>

< p > 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.
< p > 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.
