Like I said: the new way of formatting this script is not yet supported
widely enough.
Okay, so IIUC, Unicode has decided to do something that goes against the
existing practice. Given the limited available manpower in that narrow
subfield, I'm not quite sure it was the best thing to do. Using a font
with predefined ligatures is much easier to enter text.
I just looked at section 11.4 of the Unicode Standard. The first
character sequence in figure 11-2 is not a valid quadrat.
Why not?
I should have said: it's not a valid quadrat from the point of view of the
Aegyptus font, which defines ~2500 valid quadrats. Which probably means
that this combination A1 above O1 (combining a man and a house) does not
happen in practice (or happens rarely enough that it isn't yet included in
the quadrats known by that font).
And it isn't supposed to be a quadrat, AFAIU, anyway.
It is, a quadrat is a combination of two to four glyphs.
The second one are two characters that would normally be placed one
above each other, so to obtain what is displayed in the Unicode
Standard it's necessary to separate them with a zero-width non-joiner.
AFAIU, U+13431 is the joiner to be used in that case.
But it's not a joiner, it's a non-joiner. The logic is the opposite of
what Unicode decided to do: known quadrats are automatically recognized
and combined appropriately when their individual characters appear one
after the other in a string. It's only when you want to avoid this that
you have to add a non-joiner.
And you didn't answer my question: does LibreOffice with the Aegyptus
font display those sequences correctly?
I'm not sure what you mean by "those sequences". The sequences in the
patch are rendred correctly. The sequences in figure 11-2 of section 11.4
of the Unicode standard are not rendered correctly. See the attached two
pictures.
