    So far as I can tell, this is gibberish and ought to be

    > <META http-equiv="Content-Type" content="text/html; charset=utf-8">

    My browser seems to agree with me, but I await correction.

    According to the HTML standard (see
    http://www.w3.org/TR/html4/struct/global.html#h-7.4.4 ) the right way to specify the charset in html is to use the
    http-equiv attribute in META tag with a value "Content-Type" and put the charset
    value after the "text/html; charset=" in the value of the content attribute.
    The HTML specification does not specify the order between http-equiv and content
    attribute nither does it prohibit other attribute (such as charset=UTF-8 ) to
    be place. A good browser implementation will simply look at the http-equiv
    and the content and ignore the charset attribute of the <meta tag. The charset=
    should have no bad effect unless it specify a charset which is differ than the
    one in the content attribute.

    I believe currently Mozilla / Netscape 7 handle that correctly. I don't think
    Netscape 4.x and below handle that part correctly if my memory is right about
    the code that I reviewed 7.5 years ago when we were working on Netscape 2.0
    development. We have a bug about http-equiv and content ordering issue (if page
    place the content attribute before the http-equiv attribute) in the early
    stage of Mozilla developement. But either I or Shanjian Li fixed that for at
    least several years already. Not sure about IE.
