Moving The Hebrew Extended Block Into The SMP

[Philippe Verdy]

Effectively, if you need Arabic diacritics on top of Hebrew letters, just
use them. There will be no defect on script breaking, except in  strict
security checks for identifiers  where such usage is very unlikely or only
"aspirational".

You could as well use Latin/generic  diacritics if needed such as a
circumflex or cedilla. You could also use Latin letter-like diacritics, but
not the spacing ones, such as superscript o.

Combining characters should not ne desunified even if they are used un
several scripts, and even if those script have different directions, unless
they behave differently, i.e when they don't stack properly.

Hebrew diacritics written above or below normally don't stack vertically
but are ordered horizontally, but even in this case this can be infered
from the  base letter  which determines the effective layout  and even the
effective glyph to use for the diacritic (e.g. with the cedilla which
attaches sometimes above left instead of  below with some Latin letters
that have descenders like "g", or when some accents are added to Greek
letters and  placed on the left of capital letters instead of above).

Desunification of these diacritics however is needed when layouts are
distinguished both visually and semantically (such as the sin vs. shin
dots), and when their normalisation would cause major problems  requiring
systematic use of CGJ to block their reordering.

So don't fear using Arabic points or Latin accents, on top of Hebrew
letters they will be interpreted correctly in their Hebrew context, and by
themseves those combining diacritics have no direction (for the Bidi
algorithm which preverves the combining clusters).
