|

| 45 |
|
|---|
| 46 | <p> The QGb18030Codec class provides conversion to and from the Chinese
|
|---|
| 47 | GB18030/GBK/GB2312 encoding.
|
|---|
| 48 | <p>
|
|---|
| 49 | <p> GBK, formally the Chinese Internal Code Specification, is a commonly
|
|---|
| 50 | used extension of GB 2312-80. Microsoft Windows uses it under the
|
|---|
| 51 | name codepage 936.
|
|---|
| 52 | <p> GBK has been superceded by the new Chinese national standard
|
|---|
| 53 | GB 18030-2000, which added a 4-byte encoding while remaining
|
|---|
| 54 | compatible with GB2312 and GBK. The new GB 18030-2000 may be described
|
|---|
| 55 | as a special encoding of Unicode 3.x and ISO-10646-1.
|
|---|
| 56 | <p> Special thanks to charset gurus Markus Scherer (IBM),
|
|---|
| 57 | Dirk Meyer (Adobe Systems) and Ken Lunde (Adobe Systems) for publishing
|
|---|
| 58 | an excellent GB 18030-2000 summary and specification on the Internet.

| 67 | <p> The GBK codec was contributed to Qt by
|
|---|
| 68 | Justin Yu <justiny@turbolinux.com.cn> and
|
|---|
| 69 | Sean Chen <seanc@turbolinux.com.cn>. They may also be reached at
|

|
|---|
| 71 | Chen Xiangyang <chenxy@sun.ihep.ac.cn>
|
|---|
| 72 | <p> The GB18030 codec Qt functions were contributed to Qt by
|
|---|
| 73 | James Su <suzhe@gnuchina.org>, <suzhe@turbolinux.com.cn>
|
|---|
| 74 | who pioneered much of GB18030 development on GNU/Linux systems.
|
|---|
| 75 | <p> The GB18030 codec was contributed to Qt by
|
|---|
| 76 | Anthony Fok <anthony@thizlinux.com>, <foka@debian.org>
|
|---|
| 77 | using a Perl script to generate C++ tables from gb-18030-2000.xml
|
|---|
| 78 | while merging contributions from James Su, Justin Yu and Sean Chen.
|
|---|
| 79 | A copy of the source Perl script is available at:
