\class QTextCodecPlugin
\brief The QTextCodecPlugin class provides an abstract base for custom QTextCodec plugins.
\reentrant
\ingroup plugins
The text codec plugin is a simple plugin interface that makes it
easy to create custom text codecs that can be loaded dynamically
into applications.
Writing a text codec plugin is achieved by subclassing this base
class, reimplementing the pure virtual functions names(),
aliases(), createForName(), mibEnums() and createForMib(), and
exporting the class with the Q_EXPORT_PLUGIN2() macro. See \l{How
to Create Qt Plugins} for details.
See the \l{http://www.iana.org/assignments/character-sets}{IANA
character-sets encoding file} for more information on mime
names and mib enums.

\fn QTextCodec *QTextCodecPlugin::createForName(const QByteArray &name)
Creates a QTextCodec object for the codec called \a name. The \a name
