According to my understanding the following HTML markup should display a heart symbol, but it is not. What I am missing? I got the data about Unicode characters here: http://en.wikipedia.org/wiki/Html_special_characters#Character_entity_references_in_HTML

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Hearts</title>

<body>
&#2665;
</body>
</html>

The XML/HTML &#NNNN; notation is for decimal values. Try using the &#xNNNN; form to force it to interpret it as hexadecimal, or, alternatively, use the decimal value.

Encoded entities:

&hearts; &#x2665; &#9829;
&#x2661; &#x2764; &#x2765;

Output:

♥ ♥ ♥ ♡ ❤ ❥

Note the x required.

Without the x:
੥ ੩
੥ ੩

&hearts;

Works in FireFox/Chrome/IE. Looks like you forgot the "x" bit in your code.
