Roboto font issues in MFC based application - mfc

Question

I have old MFC based application. Recently we moved from Trébuchent to Roboto font. From that time onwards on some machines we are finding weird characters in the application.
I am using the CreateFontIndirect function to create the font. The IDE that I am using is Visual studio 2008.
This issue is not affecting the entire application. It is only affecting a few places.
I have observed a pattern in those junk characters. Is appears that it is adding 2 to every ASCII value. For example: if I want to display ABCD it is showing CDEF.
Please help me out in finding this. Thanks in Advance.
Here is my code sample :
void Render (CDC *pDC)
{
CString strText;
CFont *pFont = GetLocalFontStore()->LoadFont(_T("Roboto"), (int)(26 *fSizeFactor) , FW_EXTRABOLD, false, false);
COLORREF txtColor =RGB(255,0,0);
CRect rcTobeDrawn = CRect( (CPoint(177,172)), (CPoint(636,215)));
strText = _T(“This is my string”);
CFont *pOldfont = pDC->SelectObject(pFont);
COLORREF oldTxtColor = pDC->SetTextColor(txtColor);
int oldBkMode = pDC->SetBkMode(TRANSPARENT);
pDC->DrawText(strText, rcTobeDrawn, DT_CENTER|DT_NOCLIP|DT_VCENTER);
pDC->SelectObject(pOldfont);
pDC->SetBkMode(oldBkMode);
pDC->SetTextColor(oldTxtColor);
}
