\setupbodyfont[termes]
\setupbodyfont[pagella]
\setupbodyfont[bonum]

on windows (cambria is the opentype reference fonmt for math):

\setupbodyfont[cambria]

or when you bought lucida ot:

\setupbodyfont[lucidaot]

all have math

it's a bit more complex in the tex world: users are accustomed to seeing 
the a in $a$ becoming a math italic a and $\bf a$ getting a bold a .. 
both are in the unicode math alphabet so a macro package has to support 
both these switch driven inputs and direct unicode math (also because 
cut and paste from a pdf should work)

(the way macro packages implement that can be fundamental different)

(there is a font project under way that will provide monospaced math 
characters for editing)

if so, then that will be reflected in unicode alphabets (just make a 
string case for it)

finally came around .. but it's not a pretty font

a palatino based font looks imo better than stix

(as open type font they are around a bit longer and we have a bit more 
influence on their development)
