well, if you dump $www you can read
LWP will support https URLs if the Crypt::SSLeay module is installed. More information at <http://www.linpro.no/lwp/libwww-perl/README.SSL>.
so the first thing that comes to mind is, "Crypt::SSLeay" is not installed.

fact 1: if i run your script it does not print anything.

fact 2: after installing Crypt::SSleay (just done that) your script produces output. (a long html-document, i won´t post it because it is huge. I strongly assume you don´t have installed that module. (it needs additional libraries).

Update: In Order to get the output you want, you have to url-encode, the query-string, by using the enurl()-funtion of CGI::Enurl;
see this chart: 

Enrypt::SSLeay Installed : yes     yes            no
"doesn´t work" query     : börse   enurl("börse") enurl("börse")
"does work" query        : börse  börse         börse  
-----------------------------------------------------------------
output identical         : no      yes            no output
