Hi Peter:

Please run the following commands using the
-DBUILD_TEST=ON cmake option.

make ps #Create both -dev ps and -dev psc
make x07c #Build the 7th standard C example
examples/c/x07c -dev psc -o test.psc

When you view those test.psc PostScript results are the 855 and 2243
symbols missing from pages 9 and 13 of the results?

On Linux those symbols are rendered well (see the two attached
screenshots).  So if your Windows results do not look like the Linux
ones, then I think you need to install the 35 fonts which constitute
the standard set of PostScript fonts.  I don't have any direct Cygwin
experience, but for what it is worth, these fonts are packaged with
the package name ghostscript-fonts-std-8.11-1 on Cygwin (at least that
was the result when I searched the Cygwin package index for one of the
35 standard font file names).  I don't know how this standard set of
fonts should be installed for non-Cygwin Windows platforms (which is
the platform I assume you are using). It is these standard fonts that
the ps device driver uses for rendering text.  If you are getting any
text rendered at all from the above result then it appears -dev psc is
finding at least some of the standard set of 35 PostScript fonts, but
the problem may be that you have not installed all such fonts on your
non-Cygwin Windows platform.

@Arjen: I have noticed you already responded once, but could you do so
again with your own results from the above test for both the Cygwin
and non-Cygwin cases?  If you can replicate the Linux results for both
your Cygwin and non-Cygwin Windows platforms then I hope you can give
some advice to Peter about how you install the standard set of
PostScript fonts on that latter platform.
