Problem with ÆØÅ characters when using http headers (Web API)

In my ASP.Net Web Api I have a Get function where input info is sent in the http header. It works fine, except when the http header contains Norwegian characters like Æ, Ø and Å. This characters is transformed to æ ø Ã¥. When the same characters (Æ,Ø,Å) are sent as parameters in the URL it works fine. When testing the script on my local PC it works fine to send Æ, Ø and Å in the http header as well.

I don't know why norwegian characters can't be sent in the http header, but I guess this is an encoding / charset problem. After hours of testing I still can't find any way fo fix it.

Web.config:

<globalization fileEncoding="utf-8" requestEncoding="utf-8" responseEncoding="utf-8" culture="nb-NO" uiCulture="nb-NO" />

Open in new window


Getting Http Header:
 
private string GetHeader(string key)
{
    var header = "";
    if (Request.Headers.Contains(key))
    {
        IEnumerable<string> values = new List<string>();
        Request.Headers.TryGetValues(key, out values);
        if (!string.IsNullOrEmpty(values.First())) header = values.First();
    }
    return header;
}
 
var headerUserName = GetHeader("UserName");

Open in new window

Is it browser specific problem?

The request is using ISO-8859-1 before utf-8  the response is just utf-8. Try removing ISO-8859-1

The only solution that works for me is to UrlEncode the HTTP Header value, and UrlDecode it on the server.
