[XeTeX] Turning Arabic ligature OFF

[John Was]

Could you perhaps put \kern 1sp between the characters?  That will look 
messy on screen but you could make some unobtrusive and unwanted character 
active (say the Greek lenis if you don't need it) and then define it as 
{\kern 1sp}.  And if at some points you want to allow a line-break you could 
select another character (say the Greek asper) and define that as {\hskip 
1sp}.
