[Bioperl-l] problems with Biblio

[Jonathan Yom-Tov]

Hi,
 
I'm trying to run this script:
 
#! c:\perl\bin
# Collect documents from PubMed containing the term "Breast Cancer"
# and print them.
use Bio::Biblio;

my $biblio = new Bio::Biblio;
my $collection = $biblio->find("breast cancer");

while ($collection->has_next) { # there are underlines before next
print $collection->get_next;
}
 
but getting this error:
 
Unrecognized character \x93 at C:\..\test1.pl line 7.
 
Anyone have any idea why this is?
 
Thanks, 
Jon.
