The Word_Break property doesn't have a value Complex_Context, but I think that was just a typo in your message.
The word break and line break properties for 1,057 [:Script=Egyp:] characters are currently Word_Break=ALetter Line_Break=Alphabetic Off the top of my head, I think the best course would be to make them both the same as for most of [:Script=Hani:] Word_Break=Other Line_Break=Ideographic We would only need to use Complex_Context [:lb=SA:] for scripts that keep some letters together and break others apart (typically needing dictionary lookup). I would suspect for modern use of Egyp, that is not the case; most people would expect the characters to would just flow like ideographs, breaking between any pair: you wouldn't need to disallow breaks between a <man whose head is hit with an axe> and a <head of hippopotamus>, for example. Also, I noticed that the 14 Egyp characters with Line_Breakβ Alphabetic have a linebreak and general category properties that seem odd and inconsistent to me.
