base64 解码 utf-8

[qq_38826480]

已知: CString s = "572R5piT6YKu566x5pyA5paw5Yqf6IO95L2/55So5oyH5byV"
对其进行解码,根据http://web.chacuo.net/charsetbase64 工具, 选择字符集为utf-8 解码出来的是中文 "网易邮箱最新功能使用指引". 选择其他字符集则出现我们认为的乱码.

有高手能提供下字符集为utf-8的base64 解码 的代码吗 简而言之,就是我想把s 转成简体中文,用c/c++ 代码怎么做

#include <atlenc.h>

void Test()
{
  WCHAR wchBuff[256] = {0};

  LPCSTR szInput = "572R5piT6YKu566x5pyA5paw5Yqf6IO95L2/55So5oyH5byV";
  int iSrcLen = strlen(szInput);

  BYTE cDecOut[256] = {0};
  int iDstLen = sizeof(cDecOut);

  if(Base64Decode(szInput, iSrcLen, cDecOut, &iDstLen))
  {
    MultiByteToWideChar(CP_UTF8, 0, (LPCSTR)cDecOut, -1, wchBuff, 255);
  }

  OutputDebugStringW(wchBuff);
}

先用base64解码 http://blog.csdn.net/jhqin/article/details/5568862 然后再把UTF8字符串用MultiByteToWideChar转成unicode字符串

@oyljerry 好像是这么回事 我试试

	if((strlen(Buf64) %3) !=0) 
	{
		afxDump << "error\n";
	}
	ULONG len;//=strlen(Buf64);
	TCHAR *buffer;
	FromBase64(Buf64, &len ,&buffer);
	afxDump << len << " len\n";// 57
	WCHAR   wBuf[204]={0};
	char    szBuf[204]={0};
	MultiByteToWideChar(CP_UTF8,0,buffer,len,wBuf,len);
	WideCharToMultiByte(CP_ACP,0,wBuf,len,szBuf,len,0,0);
	afxDump << szBuf << "\n";// "ア?ユーラシア研究会 第38回定例研究会のご案内"
	delete []buffer;
