[XeTeX] List of ligatures in a font

[d fulano]

Many thanks for all the replies. 

 
I had tried to use primitives to compare fi with f{}i or simular, 
but it didnt work as the primitives were comparing the input 
before the ligatures were applied.

 
Putting in a box and comparing the width with the width of the 
idividual is perhaps an overkill for this...

 

But the LuaTex suggestion was a good one - I never used it, but 
searching on the internet for 'printing table of ligatures Luatex
produced a number of codes that apparently do it.  I will try it
as it seems to be the easiesdt way.

 

Thanks
