Hi. I am trying to use the simplefonts approach to get Euler for math, along with TeX Gyre fonts for text. I've looked at some of the past list archives and I haven't yet been able to figure this out. I use TeXLive, and my context is 2014.05.21.20140528-1 (Debian version). Here is the font blurb: \definefontfamily [myfamily] [serif] [Linux Libertine O] \definefontfamily [myfamily] [math] [Tex Gyre Schola Math] Now, I have tried changing the "TeX Gyre Schola Math" to Neo Euler, Euler and some other variants, but it doesn't work. I do have the Euler VM fonts installed on my system. I have also tried the example program given in http://www.ntg.nl/maps/32/06.pdf \definetypeface[eulermath][mm][math][euler][euler][rscale=1] \setupbodyfont [eulermath] \starttext \showmathcharacters \stoptext This works with texexec, but with context, it chokes. Could you please provide me some pointers? Thanks. Kumar
