QGb18030Codec - Conversion to and from the Chinese GB18030/GBK/GB2312 encoding
All the functions in this class are reentrant when Qt is built with thread support.</p>
Inherited by QGbkCodec and QGb2312Codec.
The QGb18030Codec class provides conversion to and from the Chinese GB18030/GBK/GB2312
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GBK has been superceded by the new Chinese national standard GB 18030-2000, which added a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.
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 Qt by Justin Yu <firstname.lastname@example.org> and Sean Chen
<email@example.com>. They may also be reached at Yu Mingjian <firstname.lastname@example.org>,
<email@example.com> Chen Xiangyang <firstname.lastname@example.org>
The GB18030 codec Qt functions were contributed to Qt by James Su <email@example.com>,
<firstname.lastname@example.org> who pioneered much of GB18030 development on GNU/Linux systems.
The GB18030 codec was contributed to Qt by Anthony Fok <email@example.com>,
<firstname.lastname@example.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
