Changing from UTF-8 to ISO-8859-1

[Andreas Ullmann]

I once asked again but did not get an answer:

how can i change the xml-encoding of my soap messages to ISO-Latin-1?

Which means, is it possible to change the charset entry:
POST /StockQuote HTTP/1.1
Host: www.test.com
Content-Type: text/xml; charset="utf-8"
...

to:
POST /StockQuote HTTP/1.1
Host: www.test.com
Content-Type: text/xml; charset="ISO-8859-1"
....


Hope my question isn't too stupid....
