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



fixed in next beta

[NTG-context] \definefontalternative breaks font switches in math

Dear typescript experts,

mode. E.g.,

$\bf a=\alpha$

did not display bold math. It turned out that this happens when I invoke 
\definefontalternative.

<*> \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
