Backing store and remapping are fundamental principles of Unicode.
They are implemented by people who want to implement the Unicode
standard.

For me, too.

I haven't been able to follow how I, the user, am confused by the
Unicode Standard. It sounds to me as though you want a "Show
Invisibles" option to disassemble Hebrew or Arabic text and display
them in LTR order without any ligation so that the user can see what
is in the backing store. That's a valid thing to want to do, but it's
a special case of rendering, which has little to do with the
algorithm.

Yes, it is. The Unicode Standard does not just encode characters. It
also provides tools for implementation.

We like Unicode. We work to make it better. Sometimes people come to
us with problems that aren't problems, or raise issues that have been
dealt with many times before. Sometimes people bring us real problems
that need real solutions. We're an intelligent bunch, methinks, and
we can tell the difference. Unicode may have warts, but it's a lot
better than ISO 2022.
