Adding “charset” to all ASP.NET MVC HTTP responses

Question

Is there an easy way to specify all \"normal\" views is an ASP.NET MVC app are to have charset=utf-8 appended to the Content-Type? View()

Answer 1

You could write an attribute for it:

public class CharsetAttribute : ActionFilterAttribute
{
    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        filterContext.HttpContext.Response.Headers["Content-Type"] += ";charset=utf-8";
    }
}

Feel free to make it a bit smarter, but that's the general idea. Add it to your base controller class and your whole app is covered.
