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
