I can't really answer the question of what it returns but I found
that I cured the same issues with Digest::MD5 by encoding the content
passed to it before to make sure that it's plain old octets and all
i.e one does:
my $content = encode( 'utf8', $res->decoded_content );
my $hash = md5_base64($content);
I am sure someone who understands more about this will be along to
explain why this is not a good idea...
