Hans, I still have some problems with my fonts in the latest beta. Maybe it has to do with the latest optimizations. I'm just wondering: in my Greek typescripts, I define several fontfeatures and connect them with featurefiles, like so (just an example, the list is longer): \installfontfeature[otf][gent] \installfontfeature[otf][kori] \definefontfeature [korinthia] [mode = node ,language = dflt ,script =latn,kern=yes,tlig=no,trep=no,kori=yes,featurefile=korinthia.fea] \definefontfeature [gentiumgreek] [mode=node,language=dflt,script=latn,kern=yes,tlig=no,trep=no, gent=yes,featurefile=gentium.fea] \starttypescript [serif] [GreekGentiumAlt] [name] \definefontsynonym [Serif] [name:GenAR102] [features=gentiumgreek] \definefontsynonym [SerifItalic] [name:GenAI102] [features=gentiumgreek] \definefontsynonym [SerifBold] [Serif] \definefontsynonym [SerifBoldItalic] [SerifItalic] \stoptypescript \starttypescript [serif] [GreekKorinthia] [name] \definefontsynonym [Serif] [name:Korinthia] [features=korinthia] \definefontsynonym [SerifItalic] [Serif] \definefontsynonym [SerifBold] [Serif] \definefontsynonym [SerifBoldItalic] [Serif] \stoptypescript The main font definition is of this form: \starttypescript[greek] \definetypeface[greek][rm][serif][\currentmoduleparameter{font}] [default][rscale=\currentmoduleparameter{scale}] \stoptypescript \usetypescript[greek] So I'm just wondering: must the "features=" be included into the \definetypeface as well? I have the impression that the different features I define are not used at all... Thomas
