If you have a content type definition in a template within a <com:THead>
block, and you use $this->setTitle('foo') from within the page class (e.g.
onPreInit), then the title tag will be inserted before the existing
content-type definition. This is problematic if the title contains UTF-8
characters as most browsers interpret the header data in sequence ...
therefore the title will be displayed before the browser knows that it
contains UTF-8 chars and the output will be garbled.
