Looks like an inherent design flaw to me.  It is rather easy to switch a 
properly developed site to UTF-8.  BTDT.

That is interesting (I did not know about the new htmlentities() default), 
but it does not refute my argument.  First, there have been versions of 
PHP 5 *before* 5.4.0.  Second, so far you have to *tell* PHP 5 what encoding 
you use; there is no automatism or assumed default encoding for source code 
(as in some other recent programming languages) – *only* in the PHP 5.*4* 
case *with* htmlentities() the default suffices.  (Such an automatism is 
considered for PHP *6*.)

That said, htmlentities() is insufficient to represent arbitrary Unicode 
characters, encoded with UTF-8 server-side, in an HTML document if the 
document encoding is not UTF-8; you would have to use htmlspecialchars() 
which has the same default parameter value since PHP 5.4.0.
