I think that maqam accidentals could be unified with other accidentals,
on the basis of their visual appearance.
There is a kind of system in the font Tempera, with accidentals meant
for 127 pitch-bend detuning. I think it would be resonable to assign
codepoints for these accidentals (some of them seem to be findings of
font's author, but others are basing on notation used by noticeable
composers). Anyway, some composers use these signs, and it provides some
glyphs for unusual usage (like for a pitches with certain fingering on
woodwinds, where the shape of the accidental may reflect rather the
additions to the fingering than to the sounding pitch).
Including Saggital notation seems reasonable, as well as extended
Helmholtz-Ellis, including glyphs for combination with numbers for
indicating detuning in cents (or millioctaves).
I would also add all the accidentals suggested by Hartmut Lemmel if some
of them are not included (I command the sorting basing on graphical
appearance), and, additionally, naturals with overtone numbers (may be
useful for brass notation).

I would suggest, instead of encoding all the ornaments with all possible
accidentals, that grace-note variants of common accidentals designed to
fit ornaments, should have their codepoints.

Probably.

Six of them are sometimes required, the same with accents. I think that
scoring application should draw any number of them basing on the actual
number of notes within tremolo-abbreviation. However, for more accents,
a narrower glyph variant would be useful.
