Hi,

I noticed the next strange behaviour. Let us create very simple file 
test.tex:
------------------
\font\bf=cmbx12
Normal text. \bf Bold text.
\end
------------------
Now include this file by plain pdftex:
------------------
\pdfximage{test.pdf}
\pdfrefximage\pdflastximage
\end
------------------
Everything is correct. No let us try to insert the file by context:
------------------
\starttext
%\font\bf=cmbx12
%Normal text. \bf Bold text.
\pdfximage{test.pdf}
\pdfrefximage\pdflastximage
\stoptext
------------------
And that is!!! Text 'bold text' is typeset with totaly different font 
from cmbx12, so it is smashed by wrong metric! See the attached file.
If I uncomment two lines, so the font cmbx12 is not only present in the 
included file, the result is correct. Where is the problem? Something 
mixing cm and lm? I though that included file comes with all font resources.

Hmmmm, now I feel it is more pdftex-related then context-related question.

i can't reproduce it here with your files, it looks ok, but the
mechanism is that the font comparison is made by the name in the 2nd
column of the map file, and only if this matches the fontname in the
embedded file, the font file given the end of the map line is taken. E.
g. one can force a probably similar problem by (devious)

\pdfmapline{cmbx12 CMBX12 <cmtt10.pfb}

Then the CMBX12 font coming with the embedded test.pdf would match
CMBX12 and this would be replaced by cmtt10.pfb. So it seems that
something must be wrong with the map file.

P.S. just found http://www.jwz.org/dadadodo/ (good for blindtext :-)

There is a (fairly serious) bug in two of the context-supplied Latin
Modern .map files:

   context-base.map:148:cmbx5     CMBX12    <cmrm.enc  <lmbx5.pfb
   original-public-lm.map:71:cmbx5     CMBX12    <cmrm.enc  <lmbx5.pfb

Of course, both lines should use CMBX5 instead of CMBX12. Fixing
that removes the problem.  It seems the bug was introduced in
ConTeXt 2005.05.25.

Greetings, Taco

I see. Thank you, Hartmut, for explanating font inclusion mechanism. I 
will cope the problem.
