Here's a link I found, which even has a character I need to play with for other projects of mine.

http://www.fileformat.info/info/unicode/char/2446/index.htm

There is a box with the Title of: "Encodings" on that page. And I am wondering about some of the rows.

I obviously need a course on this sort of thing, but I'm wondering what the difference is between "HTML Entity (decimal)" and "HTML Entity (hex)".

The funny thing is, which confuses me, I throw those characters on a web page, and they display fine. But I haven't specified any UTF-8 encoding in the php page.

<?php
$string1 = '&#x2446;';
$string2 = '&#9286;';

echo $string1;
echo '<br>';
echo $string2;
?>

Does the browser know how to display both automatically? And to make it weirder, I can only see those characters on my Mac, in Firefox. But my windows box doesn't want to show them. I've tested it in chrome, and firefox. Do I need to tell the browsers to view them correctly? Or is it an operating system modification?
