Why Nokogiri::HTML::Document#meta_encoding returns nil ?

require "nokogiri"

doc = Nokogiri::HTML::Document.new("<title> Save the page! </title>") doc.class # => Nokogiri::HTML::Document

doc = Nokogiri::HTML::Document.parse <<-eof <head> <meta name="description" content="Free Web tutorials"> <meta name="keywords" content="HTML,CSS,XML,JavaScript"> <meta name="author" content="Ståle Refsnes"> <meta charset="UTF-8"> </head> eof

I think the problem is that when nokogiri parses html, it assumes html 4.0 transitional, as is evidenced by the DOCTYPE.

I'm not sure how to get it to deal with HTML 5....
