Qt 中GBK和UTF8的转换

日前发现，直接将GBK编码QString通过toUtf8转码后发现时乱码，查找资料后发现直接转换时有问题的，写了几个函数已供使用：

#include

inline QString GBK2UTF8(const QString &inStr)
{
    QTextCodec *gbk = QTextCodec::codecForName("GB18030");
    QTextCodec *utf8 = QTextCodec::codecForName("UTF-8");

    QString g2u = gbk->toUnicode(gbk->fromUnicode(inStr));              // gbk  convert utf8
    return g2u;
}

inline QString UTF82GBK(const QString &inStr)
{
    QTextCodec *gbk = QTextCodec::codecForName("GB18030");
    QTextCodec *utf8 = QTextCodec::codecForName("UTF-8");

    QString utf2gbk = gbk->toUnicode(inStr.toLocal8Bit());
    return utf2gbk;
}

inline std::string gbk2utf8(const QString &inStr)
{
    return GBK2UTF8(inStr).toStdString();
}

inline QString utf82gbk(const std::string &inStr)
{
    QString str = QString::fromStdString(inStr);

    return UTF82GBK(str);
}
