Are you OK with the request context reporting the charset from the global pref,
even if there's an override in place? Potentially a bug, just want to make sure
you thought about this.

A good catch---that's an issue. Currently request context is owned by a profile,
so it seems logical to deal only with the global property here. But I think I
will need to fix this in the near future.
