    Hic! Wasn't ZWNJ also defined to control ligatures in non-cursive scripts
    like <f,ZWNJ,i> to instruct the renderer to NOT make a ligature between f
    and i?

    Are you saying now that sequences like <f,ZWNJ,i> and <f,ZWNJ,f> are non
    standard, without meaning, because it breaks *now* with the new change in
    Unicode rule D17 that changed the Unicode character model ?

    If so, what is the proposed ignorable control to specify to a renderer that
    it should NOT join <f,i> or <f,f> with a ligature?
    Same thing for <f,ZWJ,i> to instruct the renderer that it SHOULD better join
    the two grapheme clusters into a ligature...

    What did I miss there?
