Hi all,

First I admit that I've never understood the typescript part of ConTeXt...
I've been using the following recipe for boldmath.
The latin letters appears fine in bold italic font, but the greek letters do
not appear.
---------------------------
\definetypeface [boldmath] [mm] [boldmath] [latin-modern] [modern]
[encoding=texnansi]
\setupbodyfont[10pt]

\starttext
$a b c \alpha \beta \phi$

$\bi a b c \alpha \beta \phi$
\stoptext
---------------------------

Looking at the log file, I found the following error message:

---------------------------
Missing character: There is no α (U+03B1) in font LMMath10-Regular!
Missing character: There is no α (U+03B1) in font LMMath10-Regular!
Missing character: There is no β (U+03B2) in font LMMath10-Regular!
Missing character: There is no β (U+03B2) in font LMMath10-Regular!
Missing character: There is no ϕ (U+03D5) in font LMMath10-Regular!
---------------------------

Are you using MkIV? If so, an easier solution will be to use an opentype math font, like xits or cambria or asana math. Then you can simply use

$\bf a \alpha$

to get bold math.
