we should note also http://www.w3.org/TR/html4/charset.html#h-5.2.2.
the document says:

	To sum up, conforming user agents must observe the following
priorities when determining
	a  document's character encoding (from highest priority to lowest):
	1. An HTTP "charset" parameter in a "Content-Type" field.
	2. A META declaration with "http-equiv" set to "Content-Type" and a
value set for "charset".
	3. The charset attribute set on an element that designates an
external resource.

Thus, hard coding "charset=utf-8" in http header will bring other
problem
because that coding disables a line in html header such as:
	<meta http-equiv="Content-Type" content="text/html; charset=Shift_JIS">
