Dear typescript experts,
in an earlier Email I reported, that the font switches did not work in math mode. E.g.,
$\bf a=\alpha$
$\bi a=\alpha$
did not display bold math. It turned out that this happens when I invoke \definefontalternative.
Normaly \bf is defined like this:
*\show\bf
> \bf=\protected macro:
->\ifmmode \mathbf \else \normalbf \fi .
<*> \show\bf
After using \definefontalternative it looks different:
*\show\bf
> \bf=\protected macro:
->\setcurrentfontalternative {bf}.
<*> \show\bf
Minimal example:
% \definefontalternative [sb] % <-- uncomment me to break bold math
\starttext
$\bf 3x^2+7x$
\stoptext
How to avoid this? Thanks for advice,
Florian
