[users@httpd] Add HTTP header charset from HTML meta tag?

[David Lane <da...@gmail.com>]

Hello,

I'm looking for a way to handle a body of existing HTML which is encoded
inconsistently.  On the basis that the meta tag is likely to be correct, I'd
like to use that to set the HTTP content-type header's charset.  I have
Googled for solutions, and checked the module documents, and I don't see a
way to do what I have in mind.  I found a number of ways to set the header,
which seem to be "more correct" and would be fine in a better situation
(.htaccess files, changing file suffixes, etc.), but the tangle of existing
content, CMS, users and maintenance makes me lean toward a server-based
solution.  Did I miss something obvious?

David.

Hello Nick, I forgot to thank you for this.  The mod_proxy_html module does
do almost exactly what I want.  I'd rather keep the meta tag in place to
placate people concerned about the local file save issues, but other than
that, I'm golden.  Thanks.

If it's too inconsistent to automate, there's no really good solution.

mod_xml2enc nearly does what you want: it'll sniff the encoding from the <meta>
if the server doesn't set charset.  If you just chop out the libxml2 detection
(xmlParseCharEncoding) it'll do exactly what you need.  Alternatively you can
use it together with a libxml2-consumer module like mod_proxy_html, which
both deals with the charset issue and offers explicit <meta http-equiv> support.
