Hi all,
 
How can I get boldface characters and symbols  (\bf)  in mathmode.
I'm using mkiv from TexLive 2012.
I use palatino, but also would like to use palatino with euler.
Hope somebody can help me out.
 
I us the follwing definitions:
 
\starttypescript[palatino] [texnansi,ec,qx,t5,default]
\definetypeface [palatino] [rm]  [serif] [palatino] [default]
\definetypeface [palatino] [mm]  [math]  [palatino] [default]
\definetypeface [palatino] [ss]  [sans]  [modern]   [default] 
\definetypeface [palatino] [tt]  [mono]  [modern]   [default] 
\stoptypescript

1. MkIV doesn’t need a font encoding.

2. ConTeXt already provides typescripts for Palatino (or to be true Pagella).

3. You can enable bold characters with the \bf command.

\setupbodyfont[palatino]

\starttext
\startformula
A \Delta : {\bf A \Delta} : A \Delta
\stopformula
\stoptext
