[lltx] broken dash ligatures

[Stephan Hennig]

Hi,

I'm observing broken dash ligatures with certain Microsoft fonts
(including Cambria).  The attached code tests the -- and --- ligatures
on a number of fonts distributed by TeX Live, the Google font library
and Windows 7.  The ligatures work for the TeX Live and Google fonts,
but fail for all but one Windows 7 fonts (Franklin Gothic Medium).  The
PDF file can be downloaded at
<URL:http://home.arcor.de/stephanhennig/Downloads/dashes.pdf>, ca. 200 kB.

Is this a known problem?

Best regards,
Stephan Hennig
