1.unicode编码字符转 utf-8中文汉字：

#include <atlstr.h>
bool UnicodeToChinese(string str, CString&  cstr)
{
	int i = 0;
	int j = 0;
	int len = 0;

	len = str.length();
	if (len <= 0)
	{
		return false;
	}

	int nValue = 0;
	WCHAR * pWchar;
	wchar_t* szHex;
	char strchar[6] = { '0','x','\0' };

	for (i = 0; i < len; i++)
	{
		if (str[i] == 'u')
		{
			for (j = 2; j < 6; j++)
			{
				i++;
				strchar[j] = str[i];
			}

			USES_CONVERSION;
			szHex = A2W(strchar);

			StrToIntExW(szHex, STIF_SUPPORT_HEX, &nValue);
			pWchar = (WCHAR*)& nValue;

			cstr = cstr + pWchar;

		}
	}
	return true;
}

void test3() {
	//待雪初平和望断秋高
	string  m_Unicode = "\\u5f85\\u96ea\\u521d\\u5e73\\u548c\\u671b\\u65ad\\u79cb\\u9ad8";
	CString m_UnicodeToChinese;

	UnicodeToChinese(m_Unicode, m_UnicodeToChinese);

	cout << m_Unicode << "\n" << "UnicodeToChinese:" << "\n";
	wcout << m_UnicodeToChinese.GetString() << endl;

	//CString c_name = _T("li");
	//所以CT2A其实就是CW2A就是将Unicode转换为多字符集ASCII，也可写成CW2A
	std::string str = CT2A(m_UnicodeToChinese.GetString());
}
