Hi Wolfgang, I’m afraid LMTX cannot use \ss and \cg fonts in this sample (on Win7): \definefontfamily[mainface][rm][TeX Gyre Heros] \definefontfamily[mainface][mm][TeX Gyre Termes Math] \definefontfamily[mainface][ss][Gill Sans MT][tf=file:GIL_____.TTF] \definefontfamily[mainface][tt][Cousine] \definefontfamily[mainface][cg][Arial Narrow][tf=file:ARIALN.TTF] \setupbodyfont[mainface] \startbuffer \ConTeXt\ is awesome!\par \stopbuffer \starttext \startTEXpage[offset=1em] \getbuffer \ss\getbuffer \tt\getbuffer \cg\getbuffer \stopTEXpage \stoptext The fonts are there (as reported in https://mailman.ntg.nl/pipermail/ntg-context/2019/094955.html). I don’t know whether this issue could be fixed. Many thanks for your help, Pablo -- http://www.ousia.tk
