From a Postscript neophyte...

I understand that some PC software is in the habit of creating Postscript files
which contain ^D characters, to make printing via serial connections work.
I have various software packages on my SPARCStation which print, fax, and view
Postscript files, and some of these packages don't like finding ^D characters
imbedded in the Postscript.  I'd like to use a simple filter to get rid of the
^D characters.

Can anyone tell me whether it's safe to strip out all ^D characters from an
arbitrary Postscript file?  Is it possible for a Postscript file to have
^D characters that can't be stripped out?  For example, is there a way to
imbed bitmaps or other binary data using non-printable characters?

Should my filter be a little smarter, and only filter out ^D characters that
show up at the beginning of the file?  Is there any software which is
creating Postscript files with a ^D at the end as well?

Thanks for any advice,
