I'm not sure if I'm sumitting this the right place or if this is just a local problem not affecting any other, but I have the following problem:

While using Internet Explorer 7 (IE7), the method getPreferredCharsets() in the class HTTPCharsets (http.py) returns 'iso-8859-1' and not 'utf-8' as expected. As far as I know, IE7 does not set the HTTP_ACCEPT_CHARSET in the request. Reading the source I would expect that no HTTP_ACCEPT_CHARSET should result in a return value of 'utf-8'.

At least on my system the line 996 of /lib/python/zope/publisher/http.py

   header_present = 'HTTP_ACCEPT_CHARSET' in self.request

sets header_present = True, even if self.request does not contain 'HTTP_ACCEPT_CHARSET'!

Suspecting a problem with the line, not understanding why, I changed it to:

   header_present = 'HTTP_ACCEPT_CHARSET' in str(self.request)

This resolves my problem.

Other charset related settings I have changed:

Have set sys.setdefaultencoding('utf-8') in /usr/local/lib/python2.4/site.py.
Have set management_page_charset='utf-8' as property of / in ZMI.
Have set default-zpublisher-encoding utf-8 in etc/zope.conf.

Adding for debug in /lib/python/zope/publisher/http.py (around line 1000):

    print type(self.request)

returns:

    <type 'instance'>
