    I don't know enough about them to make such a proposal, but they are
    used in Persian music. And it turns out to be problem on the LilyPond
    list not having the glyphs in a Unicode font.

    I know them from the thesis by Hormoz Farhat, "The Dastgāh Concept in
    Persian Music", which says Ali Naqi Vaziri devised them for use in E24
    (24-ET, 24 equal temperament). But they are now used to indicate
    Persian style intermediate pitches, not tied to any particular tuning
    (though Farhat's values suggest traditional music uses Pythagorean
    tuning, for practical music purposes the same as E53).

    This page

    shows what they look like:
      
      

    Namely, as a horizontally mirrored flat with the loop (resp. a sharp
    with the two horizontal lines) changed to a >.
