Good point, but is the ZWNJ control supposed to be used as a base character with a defined height? I thought it was just a control for indicating where ligatures are preferably to avoid when rendering, leaving it fully ignorable if the renderer has no other option than rendering the ligature. For this application, the following character was a base character.
Other uses of ZWNJ before diacritics are in Indic scripts, or in the Hebrew proposals (in Public Review for Meteg), to control the meaning of the following character.
So I do think that the LateX2e "compound word mark" should map to <ZWNJ,INVISIBLE LETTER> rather than just ZWNJ...
The "(-)burg" abbreviation as "(-)bËg" (with a non-spacing but non-combining breve) should then be encoded with the invisible letter, in combination with ZWNJ to make it non-spacing.)
Since INVISIBLE LETTER is spacing, wouldn't it make more sense to define a ZERO WIDTH INVISIBLE LETTER than to have some weird meaning to ZWNJ that makes it unspace a space? ZWIL seems like a pretty useful thing, to me (if we agree that IL is useful in the first place).
