Better font rendering for OpenGL ?

We are using a specialized font for our application (for GD&T notations).

When rendering the text using OpenGL the font is not displayed properly (compared to GDI or even inside Word), there are some additional spaces (1, 2 pixels ) between characters of the rendered string.

Code snippet of what we are doing, we are using bitmap font, I might see if it is possible to hackuse in outline fonts instead.

// create the font and openGL list for he font
HDC hDC = wglGetCurrentDC();

LOGFONT logFont;
strcpy( logFont.lfFaceName, m_FontName );


CDC* cdc = GetDC();
HDC hdc = cdc->GetSafeHdc();

int pointPerInch = 72;
int deviceCaps = GetDeviceCaps( hdc, LOGPIXELSY );

logFont.lfHeight = -MulDiv(fontProperties.m_FontSize, deviceCaps, pointPerInch);
logFont.lfWidth = 0;
logFont.lfEscapement = 0;
logFont.lfOrientation = 0;
logFont.lfWeight = m_IsFontBold ? FW_BOLD : FW_REGULAR;
logFont.lfItalic = m_IsFontItalic ? TRUE : FALSE;
logFont.lfUnderline = FALSE;
logFont.lfStrikeOut = FALSE;
logFont.lfCharSet = DEFAULT_CHARSET;
logFont.lfOutPrecision = OUT_DEFAULT_PRECIS;
logFont.lfClipPrecision = CLIP_DEFAULT_PRECIS;
logFont.lfQuality = DEFAULT_QUALITY;
logFont.lfPitchAndFamily = FF_DONTCARE | FIXED_PITCH;

newfont = CreateFontIndirect(&logFont);
if (newfont) 
{
	SelectObject(hDC, newfont);
	glFontListBase = ::glGenLists(255);

	if (glFontListBase) 
	{
		::wglUseFontBitmaps(hDC, 0, 255, glFontListBase);
	} 

}
else
{
	glFontListBase = 0;
}

//...
glRasterPos3f( pos.x, pos.y, pos.z );
glListBase( glFontListBase);
glCallLists( strlen( text ), GL_UNSIGNED_BYTE, text );

Thanks.
