Change ASP.NET response encoding from UTF-8 to ISO-8859-1?

Hi there,

I am building an application which requires the response

Content-Type

Content-Type

to be

text/plain;charset=ISO-8859-1

text/plain;charset=ISO-8859-1

instead of

text/plain;charset=utf-8

text/plain;charset=utf-8

.

If I force this with:

Response.ContentType = "text/plain;charset=ISO-8859-1";

Response.ContentType = "text/plain;charset=ISO-8859-1";

ASP.NET returns a 406 to all responses. There is no

Accept

Accept

header coming from the client.

How may I achieve this?
