Composing Hebrew diacriticals

[Eli Zaretskii]

AFAICS, Hebrew diacriticals are not currently composed with
consonants, even in the pre-bidi display.  Is that true?

If it's true, what will it take to construct the appropriate
composition rules for the diacriticals?

I tried to read composite.el and some of the files in lisp/language
that appear to use its facilities, but quickly got lost, probably
because I know to little about this matter.  The ELisp manual also
doesn't document these facilities, unfortunately.
