MFC project using Unicode encoding, reading text data garbled conversion function

When MFC projects use Unicode, cstdiofile.readstring reads that the data is Unicode encoded and must be converted or garbled

Convert byte data to Unicode encoding

int Chartounicode (char *pchin, CString *pstrout)
{
int Nlen;
WCHAR *ptch;

if (Pchin = = NULL)
{
return 0;
}

Nlen = MultiByteToWideChar (CP_ACP, 0, Pchin,-1, NULL, 0);//CP_ACP is the local machine native property

Can be modified into the specified language GB2312 936. Shift-jis 932 UTF-8 65001.
Ptch = new Wchar[nlen];
MultiByteToWideChar (CP_ACP, 0, Pchin,-1, Ptch, Nlen);
Pstrout->format (_t ("%s"), Ptch);

delete [] ptch;

return nlen;
}

Implementation of CString coding changes. Make it possible to display the cost of language.

void function (CString &str)
{
Char *szbuf = new Char[str. GetLength () +1];

int i;
for (i = 0; i < str. GetLength (); i++)
{
Szbuf[i] = str. GetAt (i);
}
Szbuf[i]= '/0 ';
Chartounicode (Szbuf, &STR);

delete []szbuf;
}
