The internal mptopdf converter in MkIV omit some glyphs in the labels.
Here's a minimal example (test.tex):
\starttext
\externalfigure[testfig.1][frame=on]
\blank
\externalfigure[testfig-1.pdf][frame=on]
\stoptext
And testfig.1 is produced by testfig.mp
Any particular reason that you are compiling metapost files using mp and
then including them in ConTeXt rather than directly using any one of the
inbuilt ConTeXt environments for handling mp (\startMPcode, \useMPgraphic,
\processMPbuffer, etc.)
beginfig(1)
label(btex $\Omega$ etex, (0,0));
currentpicture := currentpicture scaled 5;
endfig;
end
Here's testfig.1 to save a step in debugging:
%!PS
%%BoundingBox: -18 -18 18 18
%%HiResBoundingBox: -17.98805 -17.0195 17.98798 17.0195
%%Creator: MetaPost 1.803

-17.98805 -17.0195 moveto

%%EOF
Then do:
mptopdf testfig.1
context test.tex
xpdf test.pdf
The first framed box, using the internal mps->pdf conversion, is empty.
The second framed go, using the pdf file produced by mptopdf, correctly
contains \Omega.
Try adding
prologues := 2;
or
prologues := 3;
in your mp file.
