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 QStringList QTextCodecPlugin::names() const    Returns the list of MIME names supported by this plugin.    If a codec has several names, the extra names are returned by aliases().    \sa createForName(), aliases()*//*!    \fn QList<QByteArray> QTextCodecPlugin::aliases() const    Returns the list of aliases supported by this plugin.*//*!    \fn QTextCodec *QTextCodecPlugin::createForName(const QByteArray &name)    Creates a QTextCodec object for the codec called \a name. The \a name    must come from the list of encodings returned by names(). Encoding    names are case sensitive.    Example:    \code        QList<QByteArray> MyCodecPlugin::names() const        {            return QList<QByteArray> << "IBM01140" << "hp15-tw";        }        QTextCodec *MyCodecPlugin::createForName(const QByteArray &name)        {            if (name == "IBM01140") {                return new Ibm01140Codec;            } else if (name == "hp15-tw") {                return new Hp15TwCodec;            }            return 0;        }    \endcode    \sa names()*//*!    \fn QList<int> QTextCodecPlugin::mibEnums() const    Returns the list of mib enums supported by this plugin.    \sa createForMib()*//*!    \fn QTextCodec *QTextCodecPlugin::createForMib(int mib);    Creates a QTextCodec object for the mib enum \a mib.    See \l{http://www.iana.org/assignments/character-sets}{the    IANA character-sets encoding file} for more information.    \sa mibEnums()*//*!
