I saved it as a PDF and emailed it to a Swedish friend, but all he got when he viewed the image was an empty rectangle.  It seems the trouble is that somewhere in the mail system, probably in their Windows mail reader, text lines in the PDF were converted from Unix style NL termination to DOS style CR/NL termination.  Sure enough when I converted the file on my system using the command:

At this point all I know is this....

Any PDF file to which I apply the conversion results in what you describe.  A PDF file contains binary information.  As such, I don't think the experiment is valid.

      The Dos2unix package includes utilities "dos2unix" and "unix2dos" to
       convert plain text files in DOS or Mac format to Unix format and vice

A PDF isn't a plain text file.

I would ask the recipient to check the file size they have received.
