When I read your post I knew nothing about HarfBuzz though I think I
remember having seen the name somewhere.
I have found the following page.
However, even if HarfBuzz can already do all that I am suggesting that a
"not yet available and maybe never available" 1456 middleware system
could do, neither of them can do it today because to do so first the
Unicode Technical Committee would need to have agreed a format so that
an end user of Unicode could write a Unicode "plain text" message that
would provide the instructions to whichever of those two systems were
running in the rendering system.
Those would be instructions that would be regarded by the rendering
system as software to run in the virtual machine that is simulated in
the rendering software so as to draw a custom character.
If the encoding using 7-bit ASCII printing characters that I used in
2000 (as adapted and extended for this situation) were implemented using
tag characters that could be one way to achieve progress.
Which character to use as a base character for the sequence of tag
Preferably one that already exists so as to get things going more
One that makes it clear that such a sequence of instructons is in a text
Could U+FFFC OBJECT REPLACEMENT CHARACTER be used as the base character
for such a sequence of tag characters that are providing instructions to
a virtual machine as to how to draw a custom character?
