Thank you Mojca and Aditya for your answers,
I hope the mathdesign part of mtx-update.lua will end up in the
orignal file. I do not know how to use it now.
If I save this file and update with "sh firstsetup.sh --extras=all"
(or --extras=mathdesign) it seems that the mtx-update.lua is
overwritten with the version from the server. I do not know howto
upgrade with mtx-update.lua without firstsetup.sh.
About the fourier fonts. Is there a lot of work to do in math-vfu.lua
to get it to work? I looked into that file, but it was a bit hard to
understand what is needed...
Maybe it is hard work to get the fonts working, but I really think
that if we have several text+math fonts easily available in the
minimals that will make (new) users very happy.
it depends ... if the font is in tex default encoding then it's only a
matter of adding a small table
I'm not 100% sure how it works wth font encodings, but the fourier doc
(http://mirror.ctan.org/fonts/fourier-GUT/doc/latex/fourier/fourier-doc-en.pd...)
says that the fonts are _fully_ T1 encoded.

PS: Hans, do you have any comments about the mathdesign patch
suggested by Mojca above?
I have now manually downloaded the mathdesign fonts (and the charter
fonts, not available on the server it seems)
The fonts gets used, but I get upright math letters instead of italic
ones. My test file is given by
\definetypeface[charter][rm][serif][charter]     [default]
\definetypeface[charter][mm][math] [charter]     [default]
\setupbodyfont[charter,10pt]
\starttext
We define, for real $x$, the absolute value of $x$ as
\startformula
|x|=
\startcases
\NC \hphantom{-}x \MC x\geq 0,\NR
\NC -x \MC x<0.\NR
\stopcases
\stopformula
Also let $\alpha$, $\beta$ and $\Gamma$ be\dots
\stoptext
The output can be found at
http://home.imf.au.dk/mickep/mdesign.pdf
Typesetting a similar document with LaTeX I get italic math (note also
that the \Gamma is upright, I guess that this is an option that is
turned on by default by LaTeX)
http://home.imf.au.dk/mickep/lmdesign.pdf
I guess this has something to do with the following lines in math-vfu.lua
mathematics.make_font ( "charter-math", {
   { name = "file:bchr8a", features = "virtualmath", main = true },
 -- { name = "md-chr7m.tfm", vector = "tex-mr" },
   { name = "md-chri7m.tfm", vector = "tex-mi", skewchar=0x7F },
   { name = "md-chri7m.tfm", vector = "tex-it", skewchar=0x7F },
   { name = "md-chr7y.tfm", vector = "tex-sy", skewchar=0x30,
parameters = true },
   { name = "md-chr7v.tfm", vector = "tex-ex", extension = true },
   { name = "msam10.tfm", vector = "tex-ma" },
   { name = "msbm10.tfm", vector = "tex-mb" },
} )
However, I am not able guess what to change (I tried different things
available in mdbch.map).
Any help is appreciated.
Mikael
Hans, Mojca, Aditya, Wolfgang and others

1) Can anyone confirm this problem in the previous mail or point out
what might be wrong?
2) The problem Troy had with lucida, is it the same?
3) What is needed to get fourier fonts working? Is it enough adding to
math-vfu.lua an entry like
mathematics.make_font ( "fourier-math", { ...
})
with the right names for fourier? I tried this, but no math fonts is
showing up in the pdf file. In what other file should I add changes.
I'm willing to do some trial and error to get it to work...

Best regards, Mikael
