    Well, that needs researching into what UTF-8 is in W3C and HTML 4.0 terms:

    What is a character set for interchange over the Internet? Section 6.9
    answers that:

       "The "charset" attributes (%Charset in the DTD) refer to a character
       encoding as described in the section on character encodings. Values
       must be strings (e.g., "euc-jp") from the IANA registry (see
       [CHARSETS] for a complete list)."

    Specially note the "must" term above. The [CHARSETS] reference is:

           Registered charset values. Download a list of registered charset
           values from

    So it's time to go there. The URL above says:

      "The Character Sets Registry has moved to the following:"

    OK, we'll go there instead and search for UTF-8. It says:

      "Name: UTF-8 [RFC2279]
       MIBenum: 106
       Source: RFC 2279
       Alias: None"

    RFC 2279. A copy can be found at <>, or
    any other place you like and search for FEFF, BOM, ZERO WIDTH NO-BREAK
    SPACE, or the sequence "EF BB BF" there. Nothing can be found.

    I agree, but the Unicode web age is the buggy thing here, not the specific
    browser that was reported earlier to have a problem with it. That's all my
    point. One should fix the Unicode web page instead of that browser.

    I also personally belive that any browser should fix the small istakes
    made by the author (or the authoring software) in some way or other, but
    isn't it better for the author not to make the mistake, or fix it when one
    finds about it?
