Browser displays strange characters when data is loaded via AJAX, not otherwise

$.get("/ajax-terms.asp", function(d){
    $("#wrap-terms").html(d);
})

When the terms data is included directly into the document using "Response.Write" everything appears correctly, including these characters: ‘ and ’

When I request the same data via AJAX, strange symbols are returned by server (or may be the server sends the right thing but browser renders them incorrectly). This is the strange symbol: �

Any workaround?

Edit: Here are the headers for the container page:

GET /register.html

The container page contains this line:

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

This is the jQuery/Ajax request fired by the container page:

$.get("/ajax-terms.asp", function(d){
    $("body").append(d);
})

This is what I get:

GET /ajax-terms.asp

The response seems to contain ‘ and ’ correctly but not sure why it is rendered as �.

It sounds like the AJAX getting sent by your server is encoded differently from what the browser is set to. Check the headers for the incoming AJAX.
