Description:
------------
There is a glitch, that does not allow " to be used in preg_replace, not being replaced at all. Here's what I mean:

Here is a preg_replace code, the input, and output that should be received, listed below in these text boxes I filled out


Reproduce code:
---------------
$input=htmlentities('<size="100%">This is a code that will change font-size using <span> tags, user-friendly style.</size>');

// This is supposed to do the proper replaces

$output=preg_replace('/&lt;size=&quot;(.+)&quot;&gt;(.+)&lt;\/size&gt;/iU','<span style="font-size: $1;">$1</span>',$input);


Expected result:
----------------
//Now, here is what the script is supposed to output

echo '<span style="font-size: 100%">This is a code that will change font-size using <span> tags, user-friendly style.</span>';

Actual result:
--------------
echo '&lt;size=&quot;100%&quot;&gt;This is a code that will change font-size using <span< tags, user-friendly style.</span>';
