It mentions them a little bit however in the core specifications:

Probably because Unicode specifies that «it is the task of the rendering system» to select ligature glyphs on the basis of characteristic sequences of characters in the text stream.

While having found some of the mentioned oddities in an old PDF file (ffi ligature ending up as Y, ffl ligature as Z), I’m now really puzzled about actual practise.
