Subject Re: Why can't ap_send_error_response() count on charset?

Well, my message to W3C generated a thread of ten emails.
This is a short report of their toughts.
1 - There is no need to specify a meta charset in HTML documents if the
    charset is given in the Content-Type header.
    <Liam Quinn>
    But there may be an additional complication: Some 404s may be in
    other encodings than iso-8859-1. In that case, the header would
    be wrong. As long as this is just for the built-in 'last resort'
    error message that doesn't change, it's okay. But in case it's
    tagged onto any arbitrary error message, it's a problem.
    (So with Greg's fix Apache should be fine - Carlo)
    <Martin Duerst>
    BTW, a related problem is the directive 'AddDefaultCharset'.
    This adds a 'charset' parameter to *every* Content-Type that
    doesn't already have one. This means that if you have some
    gifs, they get served as Content-Type: image/gif; charset=foo.
    This is of quite useless.
    <Martin Duerst>
    (About the AddDefaultCharset problem noted by Duerst)
    The Apache documentation implies that, but it isn't actually the case in
    my testing with Apache 1.3.26.  The charset parameter only seems to be
    added for text/html and text/plain.  It's not added for image/* or
    <Liam Quinn>
2 - About the default HTML code provided for a 404:
    (Apache developers) should change <hr /> to <hr>.  <hr /> is for
    XHTML/XML only, but they've specified HTML 2.0.
    <Liam Quinn>
3 - Some of the W3C people thinks having an option 'validate error messages' in
    the validator form is a good idea, because they want to be able to validate
    all html.
