CString CXXXDlg::UTF8Convert(CString &str, int sourceCodepage, int targetCodepage)
{
  int len=str.GetLength();
  int unicodeLen=MultiByteToWideChar(sourceCodepage,0,str,-1,NULL,0);
  wchar_t * pUnicode;
  pUnicode=new wchar_t[unicodeLen+1];
  memset(pUnicode,0,(unicodeLen+1)*sizeof(wchar_t));
  MultiByteToWideChar(sourceCodepage,0,str,-1,(LPWSTR)pUnicode,unicodeLen);
  BYTE * pTargetData=NULL;
  int targetLen=WideCharToMultiByte(targetCodepage,0,(LPWSTR)pUnicode,-1,(char *)pTargetData,0,NULL,NULL);
  pTargetData=new BYTE[targetLen+1];
  memset(pTargetData,0,targetLen+1);
  WideCharToMultiByte(targetCodepage,0,(LPWSTR)pUnicode,-1,(char *)pTargetData,targetLen,NULL,NULL);
  CString rt;
  rt.Format("%s",pTargetData);
  delete pUnicode;
  delete pTargetData;
  return rt;
}

例如:
UTF8转UNICODE
  m_strUnicode = UTF8Convert(m_strUTF8,CP_UTF8,CP_ACP);
UNICODE转UTF8
  m_strUTF8 = UTF8Convert(m_strUnicode,CP_ACP,CP_UTF8);
