Scenario 3:

Apache configuration sets a default charset and sends Content-Type:
text/html; charset=iso-8859-1 even though the meta tag in the file
specifies utf8.

Luckily, this feature could be turned off. I'm not sure, what the
default config is at the moment. Also, I don't know of any webserver
that actually implements scenario 2. Mostly, specifying the charset in
the HTTP header is used by dynamic webpages (JSP, PHP, ASP), as they
allow setting the headers.


Also, why is this discussion in the Java newsgroup?
Just because Java asks programmer to specify the charset sometimes?
