Dear list, I have the following sample: \setupbodyfont[pagella] \definefontfeature[asc] [c2sc=yes, smcp=yes] \starttext \startTEXpage[offset=1em] text \doifelsecurrentfonthasfeature{asc} {yes}{no} \doifelsefontfeature{asc} {yes}{no} \doifunknownfontfeature{asc} {yes}{no}\\ \feature[+][asc] text \doifelsecurrentfonthasfeature{asc} {yes}{no} \doifelsefontfeature{asc} {yes}{no} \doifunknownfontfeature{asc} {yes}{no} \stopTEXpage \stoptext Sorry, but which is the right way to check when the font feature is being deployed? Many thanks for your help, Pablo
