The above illustrates that the current charset-detection solutions are 
starting to get old: They are not geared and optimized towards UTF-8 as 
the firmly recommended and - in principle - anticipated default.

The above may also catch a real problem with switching to UTF-8: that 
one may need to embed pages which do not use UTF-8: If one could trust 
UAs to attempt UTF-8 detection (but not "Univeral detection) before 
defaulting, then it became virtually risk free to switch a page to 
UTF-8, even if it contains iframe pages. Not?
