How do I can set `*.asp` files (Classic ASP) in a Web Site under IIS to have Response Header's Content-Type set to `text/html;charset=UTF-8`? Right now, the files are served as `Content-Type=text/html`.

An alternate approach is to add `<% Response.Charset = "UTF-8" %>` to every single page, but I wonder if there's a way to do it globally.

Thanks!
