problem with boldmath and MKIV

problem with boldmath and MKIV

[Peter Münster]

Hello,

The following test file doesn't give bold sections no more with latest beta:

\definetypeface[boldmath][mm][boldmath][modern]
\setuphead[section][style=\boldmath\rm\bfb]
\starttext
\section{bla $bla$}
bla
\stoptext

Could you help please?

Cheers, Peter

there is no boldmath in mkiv yet, simply because there are no (complete) 
bold math fonts to test with (or at least i didn't define them) ... bold 
in math is supported

problem with math and TeXgyre and MKIV

[Alan BRASLAU]

[-- Attachment #1: Type: text/plain, Size: 154 bytes --]

No math symbols? (see attached)
Alan

minimal example:

\usetypescript[postscript]
\setupbodyfont[postscript,rm,12pt]
\starttext
$A = \pi r^2$
\stoptext

Does anyone use math?  For I am surprised that nobody is complaining.
(recent minimals, since 8 June, mkiv)

The following minimal example

% mkiv
\usetypescript[postscript]
\usetypescript[pagella]

\starttext
default: $A = \pi r^2$

\switchtobodyfont[postscript]
postscript: $A = \pi r^2$

\switchtobodyfont[pagella]
pagella: $A = \pi r^2$
\stoptext

renders incorrectly.
1. no TeXGyre \pi (or other math symbols)
2. the math "r" is strange (outlined and unselectable under Acroread)
3. numerous error messages using libpoppler (okular, evince)

I have confirmed the buggy behaviour offline, but I'm afraid that only
Hans can fix it.

the problem is that px/tx is somewhat messy; if you change this in math-vfu

     { name = "rpxr.tfm", vector = "tex-mr" } ,
     { name = "rpxmi.tfm", vector = "tex-mi", skewchar=0x7F },

you will get pi's but also lots of warnings about missing chars in the 
vector

the only solution is that someone makes proper vectors for rpxr and 
rpxmi as i have no time now for that, aditya is away and mojca is in 
thesis mode (example vectors are in math-vfu.lua)
