Qt5文件操作_保存成"UTF-8"格式

1、

bool TdrawSvg::Save2File(char* _pcFullFileName)
{

    // https://stackoverflow.com/questions/4780507/create-utf-8-file-in-qt

    QString str = FpOwnerWebView->page()->currentFrame()->toHtml();
    //QString unicodeString = "Some Unicode string";
    QFile fileOut("C:\\zzz.svg");
    //if (!fileOut.open(QIODevice::WriteOnly | QIODevice::Text | QFile::Truncate))
    if (! fileOut.open(QFile::WriteOnly | QFile::Truncate))
        return false;

    QTextStream streamFileOut(&fileOut);
    streamFileOut.setCodec("UTF-8");
    streamFileOut << str;
    streamFileOut.flush();

    // ZC: 查到说，下面的参数是true的话 就是保存成"UTF-8 + BOM"，false的话 就是保存成"UTF-8"
    //  但是，我尝试了一下，都是"UTF-8"... 不知为啥...
    streamFileOut.setGenerateByteOrderMark(true);

    fileOut.close();
}
