The W3C only recommends the "charset" info in the meta tags section,
but it is not mandatory.
It should be, though. How can a parser parse if it doesn't know
which character set to use?
In the case of the French Red Cross page, the W3C HTML validator
detects the character set as ISO-8859-15 and reports many errors
in the HTML. Manually overriding the ISO-8859-15 and making the
validator parse the web page as ISO-8859-1 still produces the same
serious errors in the HTML code of that page.
It would be interesting to see if correcting all the HTML errors
would enable MSIE 7 beta to correctly auto-detect the character set.
