(See Uni-code Technical Report #20, “Unicode in XML and Other Markup Languages,” for more information.) " I went through TR#20 and did not find any mention that ZWJ and ZWNJ are not suitable for use with markup languages. On the contrary, ZWJ and ZWNJ are listed in TR#20 under section 4 titled "Format Characters Suitable for Use with Markup". So are ZWJ and ZWNJ characters suitable for use with markup languages such as HTML and XML? yes. A./ PS: the kind of "per-instance" ligation control isn't generally available, although one could design special XML schemas where it would be. PPS: when it is desired, for example, to suppress all ligation, it would be better to do that with some overal control rather than to use ZWNJ at all possible instances. PPPS: there's always a tension between stylistic and orthographic ligation; the rules for the latter are changing though, because people are adapting them to the limitations of software....
