PHP's htmlentities function doesn't encode ★ star

htmlentities($this->name, null, "UTF-8");

Does not encode the star (★). How can I make it encode the star?

Update: &acirc doesn't render a star. Also, I'm using:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

You can't. htmlentities does not encode all Unicode characters. But you can try some workarounds, like this one

Or you can make use of output from json_encode:

$txt = preg_replace_callback(
    '/[\x80-\xFF]{3,}/', //do not trust this, it's only example that works for small range of unicode characters, that happens to include black star 
     function($m){ 
         return str_replace('\\u','&#x',trim(json_encode($m[0]),'"')).';';
      }, "Black ★ Star"
); // Black &#x2605; Star

In PHP >= 5.4, the default value of the encoding parameter was changed to UTF-8.

If you use:

htmlentities( "★", null, "ISO-8859-1");

The star character will be converted to &acirc;.
