Currently if one puts a zero-width-space (U+200B) into an XSL-FO file 
(or specifies linefeed-treatment="treat-as-zero-width-space") it is 
rendered as a "missing character" in PDF. Is that correct, i.e. does 
this character have to exist in the font used or should the formatter 
or renderer simply remove this character? It is the second approach 
that both AntennaHouse and RenderX appear to have chosen.

I recommend that no character is output for a ZWS. The whole purpose of 
placing a ZWS into the input XSL-FO is to give layout an extra break 
opportunity, without changing the appearance of the generated document.
