How to use Process.Start () with unicode-Symbols (e.g. 😜)

Question

I am trying to run a URL with a Unicode character using Process.Start(), but it gives with Win32Exception:

An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in System.dll

Additional information: Das System kann die angegebene Datei nicht finden 

(in English: "The system cannot find the specified file")

The URL I'm trying to call is http: //💩.la (this is a valid URL, at least for Firefox 38)

After the @Codo suggestion, I changed my code:

string link = "http://💩.la";
try
{
    Process.Start(link);
}
catch (System.ComponentModel.Win32Exception)
{
    Process.Start("IExplore.exe", link);
}
