Hi Wolfgang,

Thanks for this wonderful module and functionalities, and the very good tutorials you give us!
Out of curiosity I tested the examples you sent, which all work perfetcly, but the above code with eulernova typescript seems not to give the expected result (using ConTeXt  ver: 2013.10.13 23:58 MKIV) on my installation: please see the attached PDF result of the following example:

%%% begin Wolfgang's example
\definefontfamily[mainface][rm][TeX Gyre Pagella]
\definefontfamily[mainface][mm][eulernova]

\setupbodyfont[mainface]

\starttext
Text font $math font$ and $\sin(t) = \int_{0}^t \cos(\theta)d\theta$
\stoptext
%%% end Wolfgang's example

The 'h' in mathfont is a probably a bug in the font (planck constant issue as unicode math has no italic h - sic) The large () puzzle me a bit as one would expect small ones to start with.
For the fun of it I tried using MKII and with MKIV with:
\usetypescript[palatino]
\definetypeface [palatino] [mm] [math] [eulernova] [eulernova] [rscale=1.03] 

\starttext
Text font $math font( m^{(34+23)} )$ and $\sin(t) = \int_{0}^t \cos(\theta)d\theta$
\stoptext

and the result came out correct!

I would assume that simplefonts is not understanding the TYPESCRIPT eulernova correctly!

I just look at the log  and seems that MKIV load latin modern math as a fall back. From the log
</Users/quayjay/context/tex/texmf/fonts/opentype/public/lm-math/latinmodern-math.otf></Users/quayjay/context/tex/texmf/fonts/opentype/public/lm-math/latinmodern-math.otf></Users/quayjay/context/tex/texmf/fonts/opentype/public/lm/lmroman12-regular.otf>

Using the above simplefonts method I see:
</Users/quayjay/context/tex/texmf/fonts/opentype/public/tex-gyre-math/texgyrepagella-math.otf></Users/quayjay/context/tex/texmf/fonts/opentype/public/euler/euler.otf></Users/quayjay/context/tex/texmf/fonts/opentype/public/tex-gyre-math/texgyrepagella-math.otf></Users/quayjay/context/tex/texmf/fonts/opentype/public/tex-gyre/texgyrepagella-regular.otf>

Using the above simplefonts method with \definefontfamily[mainface][mm][Neo Euler] I see:

</Users/quayjay/context/tex/texmf/fonts/opentype/public/euler/euler.otf></Users/quayjay/context/tex/texmf/fonts/opentype/public/euler/euler.otf></Users/quayjay/context/tex/texmf/fonts/opentype/public/tex-gyre/texgyrepagella-regular.otf>

This suggests to me that that simplefonts is some how trying to fall back and fails or allows a lower level method do the fall back!

But ... keep in mind that eulernova is unfinished. Although it is an official (dante funded) project, we have to wait till Khaled has found time for it which is probably less an issue with a few smal patched to the font, but making it complete is large effort.

One complication is that euler is normally a mixed-in font, so there is an upright/italic cq. distinction issue there that will always make euler a font that should be used when the domain permits it.
