<h2>Message</h2>
|
|
<div class="docbody">
|
|
<p>Your feed appears to be encoded as “<i>foo</i>”, but your server is reporting “<i>bar</i>”</p>
|
|
</div>
|
|
<h2>Explanation</h2>
|
|
|
|
<div class="docbody">
|
|
<p>The XML appears to be using one encoding, but the HTTP headers from the
|
|
web server indicate a different charset. Internet standards require that the
|
|
web server's version takes preference, but many aggregators ignore this.
|
|
Note that, if you are serving content as '<code>text/*</code>', then
|
|
the default charset is US-ASCII, which is probably not what you want.
|
|
(See
|
|
<a href="http://www.faqs.org/rfcs/rfc3023.html" title="RFC 3023 (rfc3023) - XML Media Types">RFC 3023</a> for technical details.)</p>
|
|
<p>RSS feeds should be served as <code>application/rss+xml</code>
|
|
(RSS 1.0 is an RDF format, so it may be served as
|
|
<code>application/rdf+xml</code> instead).
|
|
Atom feeds should use <code>application/atom+xml</code>.
|
|
Alternatively, for compatibility with widely-deployed web browsers, any of
|
|
these feeds can use one of the more
|
|
general XML types - preferably <code>application/xml</code>.</p>
|
|
<p>Another possible cause is the use of single quotes to delimit the charset parameter in the http header, whereas the http definition of <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec2.html#sec2.2">Basic Rules</a> only permits the use of double quotes. The result is somewhat confusing messages such as:</p>
|
|
<blockquote>
|
|
<p>
|
|
Your feed appears to be encoded as “utf-8”, but your server is reporting “'utf-8'”
|
|
</p>
|
|
</blockquote>
|
|
</div>
|
|
<h2>Solution</h2>
|
|
<div class="docbody">
|
|
<p>Either ensure that the charset parameter of the <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.17">HTTP Content-Type header</a> matches the
|
|
<a href="http://www.w3.org/TR/2000/REC-xml-20001006#NT-EncodingDecl">encoding
|
|
declaration</a>, or ensure that the server makes no claims
|
|
about the encoding. Serving the feed as <code>application/xml</code> means
|
|
that the encoding will be taken from the file's declaration.</p>
|
|
<p>The W3C has
|
|
<a href="http://www.w3.org/International/O-HTTP-charset">published
|
|
information</a> on how to set the HTTP charset parameter with various popular
|
|
web servers.</p>
|
|
<p>If you are unable to control your server's charset declaration,
|
|
<a href="http://www.w3.org/TR/2000/REC-xml-20001006#sec-references">Character
|
|
and Entity References</a> may be used to specify the full range of Unicode
|
|
characters in an feed served as US-ASCII.</p>
