Response.Redirect: Need ISO-8859-1 instead of utf-8

Peter Laan · Mar 3, 2005

I need to redirect the user to an external page and include some information
in the querystring (is this possible to do as a post instead of get?) I'm
using Response.Redirect. The problem occurs if the information contains
local characters (like åäö.) The external page can only handle ISO-8859. If
I check the browser's address bar, local characters are in 'plain' text. I
tried using Server.Encode, but then I got them in utf-8. Is it possible to
get ISO-8859-1?

Add a <meta> tag.

<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">

in <head> section
-- OR --
Add

<%@ Page ContentType="text/html; charset=...." %>

Oops!
ERRATA:

In ASP and ASP.Net, content type and charset are set independently, and
are methods on the response object. To set the charset, use e.g.:

<% Response.Charset="utf-8"%>

In ASP.Net, setting Response.ContentEncoding will take care both of the
charset parameter in the HTTP Content-Type as well as of the actual
encoding of the document sent out (which of course have to be the
same). The default can be set in the globalization element in
Web.config (or Machine.config, which is originally set to UTF-8).

For web.config / machine.config file - check the globalization element.

I would suggest -- prefer using meta tag.

Setting Response.Charset didn't work. I tried the following:

Response.Charset = "ISO-8859-1";
Response.Redirect(url);

If I enter 'pÅÄÖp' as the name, I get the following in the querystring:

name=p%c3%85%c3%84%c3%96p

The external page shows other weird characters.

Found a solution (perhaps not the easiest one, but it seems to work):

// string str will be converted to string ret.
System.Text.Encoding enc = System.Text.Encoding.GetEncoding(28591);

byte[] byteArray = new byte[str.Length];

int count = enc.GetBytes(str, 0, str.Length, byteArray, 0);

string[] cs = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b",
"c", "d", "e", "f"};

for (int i = 0; i < count; i++) {

int lb = 0;

int hb = System.Math.DivRem((int) byteArray, 16, out lb);

ret += "%" + cs[hb] + cs[lb];

}

See System.Web.HttpUtility. Unlike System.Web.HttpServerUtility, it
allows you to specify a character encoding directly.

Thanks! That's exactly what I was looking for.
