Word_Break for Hieroglyphs

Thu Dec 14 08:14:31 CST 2017

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_Break≠Alphabetic have
a linebreak and general category properties that seem odd and inconsistent
to me.

Line_Break=Close_Punctuation

General_Category=Other_Letter
