C# WPF URL/TItle from Firefox Swedish letters

I am using this code to get current URL from Firefox

            DdeClient dde = new DdeClient("Firefox", "WWW_GetWindowInfo");
            dde.Connect();
            string url = dde.Request("URL", int.MaxValue);
            dde.Disconnect();

Open in new window


It woks greate, but when entering Swedish website I get problems

Example:
Accessing http://www.binero.se/
The WPF acplication gives me
http://www.binero.se/,Sveriges v?nligaste webbhotell - Binero,

Its supose to be
http://www.binero.se/,Sveriges vänligaste webbhotell - Binero,

How can I solve this so the URL and title can show swedish letters, Å Ä Ö :)
Thanks

Btw if you are going to try this code I recommend installing NDde

I downloaded the source code for the NDde project from CodePlex, and I found that it uses ASCII encoding, and not UTF-8 or Unicode:

http://ndde.codeplex.com/

Public/Advanced/DdeContext:

       private Encoding _Encoding      = Encoding.ASCII; // This is a cached DdemlContext property.

Bob LearnedCommented:
That is an issue with Unicode encoding, and I don't see how you can get around that issue with the DdeClient.  Where are you getting the implementation for DdeClient?

The strange thing, it works when using IE but not firefox, tried also to change encoding to something else (in the webbrowser). Its set to Unicode(UTF-8) by default.
