[...] The ff-ligature prevents hyphenation with TeX Gyre Pagella, but not with MinionPro. (This is the opposite of what I reported before.)
it depends on the complexity of the ligature .. ff is not so much an issue but you can have ff + i = ffi etc and we need to deal with kerning too (it depends a bit on how the opentype features are applied and we can handle quite some weird ligature implementations)
the latest mechanism in context can deal with quite some situations but at some point has to make decisions (in order not to loose for instance kerns; double chained ligatures would result in way more overhead and is not worth the trouble)
one might wonder if we never had these f[fil] ligatures of if ancient technology had provides hundreds of them combining upto 4 characters etc etc.
Many thanks for the explanation, Hans. I see the decisions ConTeXt has to make may be compromises in some cases. Many thanks for your help again, Pablo -- http://www.ousia.tk
