Comment # 21 on bug 897284 from Johannes Meixner

Perhaps I found a possible workaround to avoid the font mess:

The basic idea behind is to make the EPS so that it does no longer
need any font (also not any standard PostScript font).

Ghostscript can be used to re-create a PostScript or EPS file from scratch
in such a way which means all text will be drawn by emitting the glyph
description directly into the page stream every time a glyph is used.
For most fonts this will result in paths, for bitmap fonts it will result
in bitmaps. Note that the output will be larger, slower to process, the
text rendering will be less consistent and, particularly at lower
resolution, of poorer quality. See the somewhat related mail thread
about "pswrite and NOPLATFONTS" on the gs-devel@ghostscript.com
mailing list - but I am really not an expert in this area
so that I could misunderstand something.

I use Ghostscript version 9.15 (from the openSUSE build service
development project "Printing") and for me it worked by using the
epswrite device without any parameters:

# gs -sDEVICE=epswrite -dBATCH -dNOPAUSE \
 -sOutputFile=diagram.epswrite.eps diagram.eps

When I exchange in doc.ps the included diagram.eps
by my new diagram.epswrite.eps and save the result
in doc.with_diagram.epswrite_eps.ps then

# gs -r75 doc.with_diagram.epswrite_eps.ps

shows the Greek DELTA character.


Ulrich Deiters,
perhaps you can make your EPS files in a similar way
to avoid any kind of font mess.

Note that depending on the Ghostscript version it may vary
if -sDEVICE=epswrite and/or -sDEVICE=eps2write produce output
that does no longer need any font - you may have to use further
parameters to enforce that kind of output.

Ulrich Deiters,
could you try it out and provide feedback whether or not it
is a usable workaround for you?
