Unfortunately, not for me.

A LaTeX file has $-1$ and includes a metapost output file,
with a label $-1$ in it. The first minus sign is displayed,
but not the second one (from included file).
The problem seems to be caused by the fact, that the minus sign
is double encoded, dvips uses code \241 and downloads the necessary
part of the font, but metapost uses code \000.

It seems to fall under the case of "characters in the EPSF file
that are not also used in the TeX file".

The fix mentioned in the referenced post did not help.

A test case with dvi and ps files is at
