CreateFont doesn't Create correct font

I have an app that allows users to select fonts from the available system fonts (Windows NT 4.0).  Some of the fonts seem to get mapped to a "default" font.  Here is a sample of the code in the OnDraw section of AppView...

AppView::OnDraw(CDC* pDC)
{

CString Font_Name,OutPut;
Font_Name = "Times New Roman"
CFont Font,*Old_Font;
Font.CreateFont(-12,0,0,0,0,0,0,0,0,0,0,0,0,Font_Name);
Old_Font = pDC->SelectObject(&Font);
OutPut = "Font name = " + Font_Name;
pDC->TextOut(50,50,OutPut);
pDC->SelectObject(Old_Font);
Font.DeleteObject();
}

This works fine, the output says...
Font name = Times New Roman
in the Times New Roman font (as would be expected), but if I set Font_Name = "WingDings", the output says...
Font name = WingDings
What should be displayed is a bunch of unreadable characters in the WingDings font.  The same thing happens with the "Script" font, and a few others.  CreateFont seems to map some fonts to their correct font, while setting others to some default font.  It makes no difference if the font is TT or not.

My question...
Why doesn't CreateFont work for some fonts, but it does for others?  Am I using CreateFont incorrectly?  I have tried setting some of the 0'ed out parameters, but I don't seem to be getting anywhere.

Oops I forgot a few lines...
there should be

CFont Font,*Old_Font;

After the CreateFont line...

Old_Font = pDC->SelectObject(&Font);

and at the end of the routine...

pDC->SelectObject(Old_Font);
Font.DeleteObject();

When the font is created, system does not always
create a font that matches parameters you
supplied exactly. Fontmapper performs
selection of font that fit most the supplied
parameters from the fontmapper point of view.
One of important parameters is charset.
You must specify  DEFAULT_CHARSET in
charset parameter instead of 0 value and you will
see wingdings characters well :)
Default charset will try to use charset default
to _font_.

Thanks, I knew it had to be something easy.  Default_Charset is the one setting I didn't try because the help file for CreateFont had a big warning to try not to use this setting.  I just checked it out and it works (not that I really want WingDings, but I do want the other fonts)
