定义

CString UTF8AndUnicode_Convert(CString &strSource, UINT nSourceCodePage, UINT nTargetCodePage){    CString        strTarget; 	    wchar_t        *pWideBuf;    int            nWideBufLen;	    char           *pMultiBuf;    int            nMiltiBufLen;    int            nSourceLen;    nSourceLen = strSource.GetLength();     nWideBufLen = MultiByteToWideChar(nSourceCodePage, 0, strSource, -1, NULL, 0); 	    pWideBuf = new wchar_t[nWideBufLen+1];     memset(pWideBuf, 0, (nWideBufLen + 1) * sizeof(wchar_t)); 	    MultiByteToWideChar(nSourceCodePage, 0, strSource, -1, (LPWSTR)pWideBuf, nWideBufLen);    pMultiBuf = NULL;    nMiltiBufLen = WideCharToMultiByte(nTargetCodePage, 0, (LPWSTR)pWideBuf, -1, (char *)pMultiBuf, 0, NULL, NULL); 	    pMultiBuf = new char[nMiltiBufLen+1];     memset(pMultiBuf, 0, nMiltiBufLen + 1);     WideCharToMultiByte(nTargetCodePage, 0, (LPWSTR)pWideBuf, -1, (char *)pMultiBuf, nMiltiBufLen, NULL, NULL); 	    strTarget.Format(_T("%s"), pMultiBuf); 	    delete pWideBuf;     delete pMultiBuf; 	    return strTarget; }

 

调用方法

UTF-8转Unicode

m_strUnicode = UTF8AndUnicode_Convert(m_strUTF8, CP_UTF8, CP_ACP);

Unicode转UTF-8

m_strUTF8 = UTF8AndUnicode_Convert(m_strUnicode, CP_ACP, CP_UTF8);
