QString中包含中文的時候， 轉爲char *

void FileEncWidget::QString2ANSI(QString text, char **pOut) {
	std::wstring wIn = text.toStdWString();
	char *pcstr = (char *)malloc(sizeof(char)*(2 * wcslen(wIn.c_str()) + 1));
	memset(pcstr, 0, 2 * wcslen(wIn.c_str()) + 1);
	int len = WideCharToMultiByte(CP_ACP, NULL, wIn.c_str(), wcslen(wIn.c_str()), NULL, 0, NULL, NULL);
	*pOut = (char *)malloc(len + 1);
	WideCharToMultiByte(CP_ACP, NULL, wIn.c_str(), wcslen(wIn.c_str()), *pOut, len, NULL, NULL);
	(*pOut)[len] = '\0';
}

當然也有這種方法：
