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.
