Request.QueryString Collection Doesn't Get Umlauts

[Axel Dahmen]

Hi,

I've created an aspx page taking a query string argument as parameter.
Although I've correctly escaped umlauts in the query string, they do not
appear in the QueryString collection. If I give:
http://myComp/myPage.aspx?q=G%FCnther

Request.QueryString[0] yields "Gnther" instead of "Günther".

What's happening?

TIA

You can convert the parameter with Server.UrlEncode before invoking the
url,then get the value of the parameter with Server.UrlDecode.
maybe help

%FC is ü in ISO-8859-1 (or -15), but ASP.NET is using UTF-8 by default
to decode request parameters (including the query string). That leaves
you with the following choices:

1. Change your application's <globalization/> element in web.config to
use ISO-8859-1 as requestEncoding (and in this case preferably
responseEncoding as well).

2. If you want to change the request encoding through code, set in it
your HttpApplication's (e.g. global.asax) Application_BeginRequest
callback:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
//This will override the <globalization/> entry with ISO-8859-1
Request.ContentEncoding = Encoding.GetEncoding(28591);
}

3. Make sure the client is using UTF-8 when encoding request
parameters. How to achieve that depends on your web client. Since
you're using a Web Form, it's most likely that the browser uses the
wrong encoding. Did you add some META tag to your Web Form, or is your
browser configured to use ISO-8859-1 exlcusively?

Thanks a lot, Jörg! You helped me a lot!

Actually, what I did was simply typing "javascript:escape('Günther')" into
the address bar of my browser. Didn't know that there were several encodings
allowed on the query string.

Now I've created a simply GET form and set the encoding to UTF-8 manually.
