That's fine if you use a new type, or profile an existing one.

But claiming that charset=... means something else before depending on

I'm ok with that. I'm not ok with treating something that has a charset 
of ISO-8859-1 silently as UTF-8, in particular when other parts of the 
platform disagree.
