Well, I've very little ConTeXt knowledge to actually understand this. My main point was that non-printable formatting characters like ZWNJ, ZWJ should be font independent i.e. when I insert a ZWNJ it inhibits the joining of Arabic letters without being printed, the font having or not having a glyph for it shouldn't affect this. In the other hand, it should be their so that when I copy the text I get it (since it is part of the input and has semantical value). Is this what we have here?
