In practice one will enable most <strong>of</strong> the features. In MkIV one can dene feature sets as<br />
follows:<br />
\definefontfeature<br />
[arab-default]<br />
[mode=node,language=dflt,script=arab,<br />
init=yes,medi=yes,fina=yes,isol=yes,<br />
liga=yes,dlig=yes,rlig=yes,clig=yes,<br />
mark=yes,mkmk=yes,kern=yes,curs=yes]<br />
Applying these features to fonts can be done in several ways, with as most basic one:<br />
\font\ArabFont=arabtype*arab-default at 18pt<br />
Normally one will do something like<br />
\definefont[ArabFont][arabtype*arab-default at 18pt]<br />
or use typescripts to set up ap proper font collection, in which case we end up with definitions<br />
that look like:<br />
