Thanks - very interesting indeed! Fontin used to be my favourite font, until I ran into this ligature problem on the Kobo. In fact, after reading your post I have checked again and "officer" is being rendered as "o cer", i.e., it is using the ffi ligature and not ff as I initially thought (in the source epub there are no ligature characters). I may add the ffi ligature to Fontin to get around this problem. In fact Fontin is the only font I have found so far which has this problem, especially with the word "officer" (common enough in the military history fiction I tend to read).
