RE: [groff] PDF problems - see attached file

[James Deri]

One difference I note, is that the font encoding changes on the 2nd page on
the pdf produced by gs 7.x (it does not happen with gs 6.51).

To see what I mean, use 'acroread' on the pdf, look at File->Document
Info->Font (note "Custom" encoding). Now page down to page 2 and repeat, a
2nd font is used this time with "Standard" encoding. The .ps file, produced
by 'grops' only has one font defined/encoded.

Cheers

Deri
