-- begin excerpt --
To address server or configuration limitations, HTML documents may
include explicit information about the document's character encoding;
the  META element can be used to provide user agents with this
For example, to specify that the character encoding of the current
document is "EUC-JP", a document should include the following  META
<META http-equiv="Content-Type" content="text/html; charset=EUC-JP">

The META declaration must only be used when the character encoding is
organized such that ASCII-valued bytes stand for ASCII characters (at
least until the META element is parsed).  META declarations should
appear as early as possible in the  HEAD element

Copied from: http://www.w3.org/TR/html4/charset.html#h-5.2.2

An excerpt from HTML 4.01 specification. So in other words you've to
organize your content such that your content till <META> tag is ASCII.
I think this is what this excerpt means.
