[XeTeX] Opentype features problem in Windows

[Juan Acevedo]

Dear all,

I am test driving a new customised Opentype Bembo Book from Monotype, who  
have added a couple of features to the font and corrected some kernings  
(JK you may remember some time ago I approached you with queries regarding  
this work). Now, unfortunately, the kerning corrections do show up nicely  
when I prepare a sample text in OpenOffice Writer, but they are not there  
to be seen when I try with XeTeX. Even worse, features that used to work  
under XeTeX with the original Bembo Book, like old style numbers and small  
caps, are now gone with the customised font. My guess is that when the  
Monotype people worked on the font, they broke something, but being no  
font expert at all, I would not even know how to explain the problem. The  
fact that OO Writer displays the right kerning seems to indicate that the  
font actually contains the corrections, now, could I tell XeTeX how to  
access them?

I am using TexLive under Windows XP, and I have no Mac at hand at the  
moment to try this behaviour. Fontspec is v.1.14, but I have also tried  
without fontspec, and the problem is the same.

Can someone give a hint as to where the problem lies?

Thanks in advance,

Juan
