Recommendation: Please learn more about such issues and correct your 
mistakes before you complain about them.

Rubbish.  Windows-1252 is not recommended /because/ it is not supported 
by the occasional old browser.  It is a proprietary character encoding, 
which may not be supported by a lot of browsers; particularly 
non-Windows based browsers (though, newer browsers on other systems have 
probably been forced to support it anyway)

They are real issues, there is no need to become agitated.  The problem 
is that character references like &#nnnn; and &#xnnnn; do not accept the 
code point of the character from the document's character encoding. 
They refer to the code point within the Unicode character repertoire 
regardless of the character encoding you're using.

Instead of using &#146; for a right single quotation mark, for example, 
you should, &#8217; (decimal) or &#x2019; (hexadecimal).

So are the the warnings you are receiving.  You have just failed to 
understand the reasoning behind them and incorrectly jumped to the 
conclusion that that are not your problem to deal with.

You may find these articles useful to help you understand the issue better.
