It's probably an issue with fonts. Do you know that fonts for printing
and displaying are different? Linux printing tool is ghostscript and
there is a bunch of fonts for it. Different fonts are using different
character sets. Default printing font in gschem is Helvetica.
(Encapsulated) Postscript file which gschem outputs is a text file and
you can look at its content and edit it. There are many symbols used in
UTF-8 to output Ω (/Omega, /Omega1, /Omegagreek, etc) and a couple of
them for µ (/mu, /mugreek). Open your eps-file and try to find them.
There are also a lot of fonts. Therefore it's not easy to find a working
combination. /mu, /Omega and Verdana work for me. So the solution could
be the following:

- open your eps-file in a text editor and look for /UTFEncoding line.
  Then you can find a charset description. There should be strings
  like /Omegagreek and /mugreek.
- change them to /Omega and /mu and look at your document in your
  postscript viewer
- if it isn't working, try to find the string:
    /gEDAFont UTFencoding /Helvetica RE
  and change Helvetica to Verdana (or maybe some other fontname)

This is the same but a bit quicker:
sed -i 's/Helvetica/Verdana/; s/Omegagreek/Omega/; s/mugreek/mu/' schematic1.eps schematic2.eps ...

You could try to find other fonts, or to install fonts from M$ (Arial or
some others).

BTW
There is also Peter C.'s gschem branch (cairo printing). Is it working?
