Browsers default to various encodings, often windows-1252 (rather than 
ISO-8859-1). They may also investigate the actual data and make a guess 
based on it.

It would not. There?s no reason to recommend any particular defaulting, 
especially not something that deviates from past practices.

It might be argued that browsers should do better error detection and 
reporting, so that they inform the user e.g. if the document?s encoding 
has not been declared at all and it cannot be inferred fairly reliably 
(e.g., from BOM). But I?m afraid the general feeling is that browsers 
should avoid warning users, as that tends to contradict authors? 
purposes ? and, in fact, mostly things that are serious problems in 
principle aren?t that serious in practice.

There?s a large amount of pages declared as UTF-8 but containing Ascii 
only, as well as pages mislabeled as UTF-8 but containing e.g. ISO-8859-1.

That?s because the server-side software (and possibly client-side 
software) cannot handle the letter ???. It would not help if the page 
were interpreted as UTF-8. If the author knows that a server-side form
