In August 2013 Aditya and Hans provided the following wizardry to include math symbols from pagella when using euler as math font. http://www.mail-archive.com/ntg-context@ntg.nl/msg71000.html (Thank you to all involved! It works fine.) \usetypescriptfile[euler] \starttypescript[mainface] \definetypeface[mainface][rm][serif][pagella] [default] \definetypeface[mainface][mm][math] [pagellaovereuler][default] \stoptypescript \setupbodyfont[mainface] \appendtoks \rm \to \everymathematics \setupmathematics[lcgreek=normal, ucgreek=normal] \starttext The text font and $\angle ABD \cong \triangle XYZ$ \stoptext Can this be achieved with the new simplefonts? I have tried the setups in this thread but the symbols do not show. John
