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 %%CreationDate: 2013.08.09:1612 %%Pages: 1 %*Font: cmr10 49.81323 9.96265 0a:8 %%BeginProlog %%EndProlog %%Page: 1 1 0 0 0 setrgbcolor -17.98805 -17.0195 moveto (\012) cmr10 49.81323 fshow showpage %%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. Aditya
