Hans,
\font\at= [c:/Windows/Fonts/arabtype.ttf]:% mode=node;script=arab;+init;+medi;+fina;+rlig;
how about also adding: 'kern' 'mark' 'mkmk' 'curs' as well as 'analyze' and maybe 'liga', 'calt', 'clig' and more
The two words I selected should work with the minimal set of features I set. And indeed, your code under \tex\generic\context\luatex DOES work. But luautfload has not been updated (and adding these features changes nothing). Javier
