Qt将中文转换成unicode字符串

 

QString CTestManager::stringToUnicode(QString str)
{
    const QChar *q;
    QChar qtmp;
    QString str0, strout;
    int num;
    q=str.unicode();
    int len=str.count();
    for(int i=0;i<len;i++)
    {
        qtmp =(QChar)*q++;
        num= qtmp.unicode();
        if(num<128)
            strout+="\\u00"; //英文或数字前加"00"
        else
            strout+="\\u";
        str0=str0.setNum(num,16);//变成十六进制数
                if(1 == str0.count()) str0 = "0" + str0;   //注意！！！
        strout=strout+str0;
    }
    return strout;
}
