No, PDF isn't text, but it has a large plain text header that frequently
fools Perl (both Mac and Unix).  I suppose a fix to the base Perl code may
be in order, maybe reading in a larger chunk of the beginning of the file
to do its checking.

}Yeah, the way I worked around using "$ls = `ls $file`;" made a few other

You don't need to if you don't want to.  In my MacPerl port of
libwww-perl-5 (http://mors.gsfc.nasa.gov/MacPerl.html),  there are routines
that convert back and forth.  They deal with all sorts of esoteric stuff
(at least they're supposed to) that you may never need, but that means they
work for the simple stuff as well.  Look in particular at
URI::URL::newlocal.
