Obviously: it is a build from CVS, 2009-10-11!! :-)

I know. I follow Emacs development since 22.0.50-CVS.

Those browsers, in my case, are configured to "Allow pages to choose 
their own characters...". Indeed, a few tests show that a few web pages 
are in UTF-8 and others in ...ISO-8859...

Firefox show that!!! :-)

"Western" is the translation of "Occidentale" (I have Firefox 3.5-it, 
obviously). In my Firefox, the menu "Visualizza | Codifica dei 
caratteri" (i.e. View | Characters encoding) shows many encodings, also 
"Europa Centrale ISO-8859-2", "Occidentale ISO-8859-15"...

As I have written, I haven't to choose explicitly that: it is 
automatically selected if the page is in UTF. :-)

It seems we are talking about different things/systems :-)

Anyway this is not very important to the release. Who does not visualize 
correctly that documentation can always change manually the encoding, 
eventually by trying.
