Right, KF8 is required for Arabic, not just for ligatures but for RTL display.

I'm just pointing out that the PW1 (and pre-'typography' update) renderer is capable of composing ligatures, but for whatever reason, does not (and apparently will never) compose them for English on that device. 'Crippled' font files is consistent with that behavior, but I am not claiming that is the only possible mechanism. In any case, it is kind of spooky behavior when compared to modern ePub renderers, which do this in their sleep.

Are there ebooks available here in mobi format that use embedded fonts? I'd like to do some experiments...
