The HTML5 validator could very well show a warning for displaying 
ISO-8859-15. HTML5 excplicitly allows such a warning. Mike, would you 
add a such a warning? Consider it a feature request from my part!

This is what HTML5 says: [1]

Authors are encouraged to use UTF-8. Conformance checkers may advise 
authors against using legacy encodings. [RFC3629]

Authoring tools should default to using UTF-8 for newly-created 
documents. [RFC3629]
  [ snip ]
Using non-UTF-8 encodings can have unexpected results on form 
submission and URL encodings, which use the document's character 
encoding by default.
