DESCRIPTION

20       The QGb18030Codec class provides conversion to and from the Chinese
21       GB18030/GBK/GB2312 encoding.
22
23       GBK, formally the Chinese Internal Code Specification, is a commonly
24       used extension of GB 2312-80. Microsoft Windows uses it under the name
25       codepage 936.
26
27       GBK has been superceded by the new Chinese national standard GB
28       18030-2000, which added a 4-byte encoding while remaining compatible
29       with GB2312 and GBK. The new GB 18030-2000 may be described as a
30       special encoding of Unicode 3.x and ISO-10646-1.
31
32       Special thanks to charset gurus Markus Scherer (IBM), Dirk Meyer (Adobe
33       Systems) and Ken Lunde (Adobe Systems) for publishing an excellent GB
34       18030-2000 summary and specification on the Internet. Some must-read
35       documents are:

43       The GBK codec was contributed to Qt by Justin Yu
44       <justiny@turbolinux.com.cn> and Sean Chen <seanc@turbolinux.com.cn>.

48       The GB18030 codec Qt functions were contributed to Qt by James Su
49       <suzhe@gnuchina.org>, <suzhe@turbolinux.com.cn> who pioneered much of
50       GB18030 development on GNU/Linux systems.
51
52       The GB18030 codec was contributed to Qt by Anthony Fok
53       <anthony@thizlinux.com>, <foka@debian.org> using a Perl script to
54       generate C++ tables from gb-18030-2000.xml while merging contributions
55       from James Su, Justin Yu and Sean Chen. A copy of the source Perl
56       script is available at:
