I want to remind people that CGJ is *not* a control character. Look at the properties; there is a listing in:
http://oss.software.ibm.com/cgi-bin/icu/ub/utf-8/?ch=034F#here It is an non-spacing mark *already*. There should be no impediment at all to using it in a sequence of other nonspacing marks in a font. If the font is smart enough to be able to place multiple accents over characters, then the incremental work necessary to handle CGJ invisibly is quite small. And it presents a possible mechanism that can be used throughout Unicode, not just for Hebrew.
