Hi Damian,

Looking at your bad-sqrt.pdf you can see that ghostscript has embedded the two 
Times-Roman 
fonts, but not the symbol font. This means that whichever viewer you use needs 
to find a useable 
symbol font itself, since it is not embedded.

In my case it has found a suitable font as s050000l.pfb. I suspect your windows 
desktop has 
access to a suitable font, but your linux desktop does not. You may find you 
need to install the 
urw-fonts package, something like:-

# yum install urw-base35-fonts

Which should let okular/evince find the symbol font.

After they have been installed you can build groff by using:-

--with-urw-fonts-dir=/usr/share/fonts/urw-base35

On the configure command.#

I attach a version using -T pdf -P-e which has all the fonts embedded which 
should look Ok in 
all viewers.

Cheers 

Deri
