LWP ends up with unreadable characters

i'm trying to use LWP on:

	http://education.yahoo.com/reference/dict_en_es/spanish/a_1;_ylt=
	AoFfUtrOQo3d1vl10ohvPPb2s8sF

when i do :

       $ua = LWP::UserAgent->new;
       $res1 = $ua->get($url,%header);
       my $page = $res1->content;

'$page' ends up with unreadable characters. the code works fine for
most sites. also, if i fetch the page with 'lynx' i get readable stuff,
and a browser's 'view source' function on the page gets a normal
result.  

ideas?
