      What you listed above pretty much covers what I had in mind. Anyway,
    it just occurred to me that we may make opentype GSUB feature for turning
    the invisible to the visible (unless there's one already) that is OFF
    by default (i.e. the nominal glyphs for them are invisible or very thin
    space). That way, ordinary programs (without special need) can
    render them invisible (or very thin space as font developers see fit)
    while specialty programs like character pickers or typesetting / word
    processing programs, MathML editors or (La)TeX/Omega/Lambda front-end
    (e.g. Scientific Word, Lyx or typical TeX shell such as WinEdit) can
    turn on the feature and show them visually.


    P.S. : Copy is being sent to opentype list as well.
