as mentioned in an earlier mail, after decades of utf in tex we should
use the normal symbols instead ... you can disable collapsing with

need to adapt
Not sure I understand your explanation.
I have been using UTF-8 as charset for my documents since 2002
(otherwise polytonic Greek was unreadable for me).
It was also more readable to use real character for em- and en-dashes
than three or two hyphens.
It took me a while since I accidentally discovered a document with a
wrong line break between a real em-dash and a point followed by a
footnote number.
So my question is what \hccode stands for?
hyphencharcode
good old tex only has \exhyphenchar, in luametatex we can tag any char
as such
in traditional tex th ehyphenation, ligature building and kerning wre
integrated, so handling - -- --- ---- ---------- is kind of complex
in luatex these stages are split but there's still messy logic wrt
successive hyphens
in luametatex the hyphenation machinery has all kind of extra controls
and the hccode mechanism was introduced as side effect of a feedback
mechanism that also can handle compound words better (althoiugh one can
of course dispute the 'better' part)
From luametatex.pdf in the distribution, I see that this is a LuaTeX
primitive, but luatex.pdf doesn’t mention it.
sure, it's a luametatex primitive, but that is true for some more, like
the detailed control of how characters are treated in various stages
