After some more investigation I think this is a bug in  
zope.pagetemplatefile: content sniffing only takes the <meta> tags for  
content-type into account. Encoding will be set according to portal rules  
but the comnbination can cause problems for some browsers (Firefox, at  
least, ignores the charset and assumes latin-1). Furthermore, the  
behaviour varies between the "classic" rendering and views. As views can  
be configured without a dedicated class I can't see a CMF solution to this.

To test simply add some non-ascii to the "ursa" or "were" main_templates  
and call the @@view.html in Firefox. For some reason CMFDefault's  
@@view.html still renders correctly. I guess this must be related to the  
__init__ in ursa globals. This probably needs patching so the behaviour is  
the same. At least we've got tests for this.

I don't think depending on the meta declaration is the right approach.  
I've seen it used incorrectly very often and it's supposed to be a hint  
for the browser but will be overridden by the content-type in the header.  
Better to add proper detection for the HTML Doctype in  
zope.pagetemplate.pagetemplatefile. I'm not sure about the charset - I  
think there's a way to check for the character encoding "manually" using  
the BOM and this should be used with the meta declaration as a fall-back  
and there should be an error if there is a mismatch. Should I submit a bug  
on this?
