I tried

\starttext
\startMPenvironment 
\ss
\enableencoding [il1]
\stopMPenvironment 
\startuseMPgraphic{test}
label(btex élève etex,origin);
\stopuseMPgraphic
\useMPgraphic{test}
\stoptext

and it doesn't display ``é'' and ``è''.

When I look at the mpx file, I see

begingroup save _p,_r,_s,_n; picture _p; _p=nullpicture;
string _n[];
vardef _s(expr _t,_f,_m,_x,_y)=
  addto _p also _t infont _f scaled _m shifted (_x,_y); enddef;
_n0="cmss12";
_s("lve",_n0,1.00000,0.0000,0.0000);
setbounds _p to (0,0.0000)--(13.3110,0.0000)--
 (13.3110,8.3022)--(0,8.3022)--cycle;
_p endgroup
mpxbreak

so presumably, the problem is cmss12.

Can you explain how ``é'' is handled? In LaTeX, 
é becomes \'e (with the input encoding latin1) and
this is translated into some position in the font,
or some combination of characters. With cmss12, LaTeX
would map \'e to some \accent combination.

What is the context position on this matter?
