Use unicode (UTF-8) charset instead of ISO-8859-1 in admin console pages
Description
All of the admin console pages are set to ISO-8859-1 as the charset. This confuses some browsers when there are characters on the page that do not fit into ISO-8859-1. The non-ascii characters are encoded in UTF-8 anyway, so setting the charset to UTF-8 is more proper anyway.
