I’m reading “Dive into html5” and in
[http://diveintohtml5.org/semantics.html#encoding](http://diveintohtml5.org/semantics.html#encoding)
, it says every page should contain ,
otherwise it’s subject to security vulnerabilities (http://
[code.google.com/p/doctype/wiki/ArticleUtf7](http://code.google.com/p/doctype/wiki/ArticleUtf7)). I don’t see being generated in my application.html.erb (in
rails3) Is there a reason behind this?

because rails sets the content-type header (which, as the article you
linked to notes, is the preferred mechanism for this)
