In August 2013 Aditya and Hans provided the following wizardry to include math symbols from pagella when using euler as math font.

(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.

The example below works but you have to wait a few days because there was a bug in the code when \definefallbackfamily was used with a math font. \definefontfamily [mainface] [serif] [DejaVu Serif] \definefontfamily [mainface] [sans] [DejaVu Sans] \definefontfamily [mainface] [mono] [DejaVu Sans Mono] \definefallbackfamily [mainface] [math] [TeX Gyre Pagella Math] [range=0x02100-0x02BFF,force=no] \definefallbackfamily [mainface] [math] [TeX Gyre Pagella Math] [range=0x1D400-0x1D7FF,force=no] \definefallbackfamily [mainface] [math] [TeX Gyre Pagella Math] [range=0x0210E] \definefontfamily [mainface] [math] [Neo Euler] \setupbodyfont[mainface] \appendtoks \rm \to \everymathematics \setupmathematics[lcgreek=normal, ucgreek=normal] \starttext The text font and $\angle ABD \cong \triangle XYZ$ \stoptext Wolfgang
