javascript - How to force XMLHttpRequest to use ISO-8859-1 charset only?

Question

I have ISO-8859-1 database, so I like to exchange requests entirely in this codepage. So, how to set content-type for AJAX requests in the right way?

Answer 1

Even though it's bad to do (bunch of comments above), this would work:

var xhr = new XMLHttpRequest(); 
xhr.open("GET", path, false);
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded; charset=ISO-8859-1')
