Apart from creating some new virtual euler font with accents I can not 
see any solution. Beforementioned commands (\acute ...) do not work in 
\mbox and \hbox in math mode (writes about '{' and '}' missing).

Another strange thing. After this sequence:

\usetypescript [modern-base] [t2a] % just for example
\setupbodyfont [modern]

\definetypeface[mytf][mm][math][euler][euler]

\startbuffer
$$\sqrt{\acute{a}+\bar{b}+\dot{c}}$$
\stopbuffer

\starttext
\getbuffer
\switchtobodyfont[mytf]
\getbuffer
\switchtobodyfont[modern]
\getbuffer
\stoptext

Third formula remains roman. Why so?
