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?

I cannot confirm since I get Assertion failed: (l_fonts[1] != 0), function read_char_packets, file ../../../source/texk/web2c/luatexdir/font/luafont.c, line 881. MTXrun | fatal error: no return code, message: luatex: execution interrupted

2) The problem Troy had with lucida, is it the same?

Might be related, but solving one won't solve the other one.

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?

If the font comes with some weird encoding, then you also need to write the whole slot-to-unicode mapping. See for example: fonts.enc.math["tex-sy"] = { [0x0002D] = 0x00, -- - [0x02212] = 0x00, -- - -- [0x02201] = 0x00, -- complement -- [0x02206] = 0x00, -- increment -- [0x02204] = 0x00, -- not exists --~ [0x000B7] = 0x01, -- cdot [0x022C5] = 0x01, -- cdot [0x000D7] = 0x02, -- times [0x0002A] = 0x03, -- * [0x02217] = 0x03, -- * [0x000F7] = 0x04, -- div [0x022C4] = 0x05, -- diamond [0x000B1] = 0x06, -- pm [0x02213] = 0x07, -- mp There is 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" }, } ) But I'm not sure if all of the fonts are right (I need to figure out how to compile the example in the first place). A way to check is to run the following with MKII and compare both for example: \showfont[md-chr7m.tfm] \showfont[rm-lmr10] Mojca
