Problems with special letters like ÆØÅ from html code to listbox

Question

Hi

I'm trying to parse a HTML page where I ran into a small problem(well sort off big to me). F.eks lets take the letter Ø. In the HTML code the Ø = "Ø".

I thought I could replace the string like this:
line = line.Replace("Ø", "Ø").Replace("Ø", "Ø").Replace("Ø", "Ø");

But when I add the string to the listbox, it comes out like f.eks: "DD8;ivind".

How can I print out special characters like this in a correct way?

Also, I'm going to insert this data into a mysql database, how will this look like? When the Ø is "Ø", it becomes the same in the database as well.

If it is to any relevanse, I read the page like this:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.AllowAutoRedirect = true;
req.Method = "GET";
req.Timeout = 6000;
WebResponse res = req.GetResponse();
StreamReader sr = new StreamReader(res.GetResponseStream());
page = sr.ReadToEnd();
sr.Close();
res.Close();
parsePage();

and the  web page content-type is:
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1"> 

I hope there is an easy way to my problem.
