Bug description:htmlspecialchars() encodes & and — in a wrong way

Description:
------------
The function htmlspecialchars() encodes the & character even if it is part
of some html entity like & or — .

The workaround is also difficult because the function doesn't allow to
disable replacing of the & symbol (I believe it should).

PHP version 



Test script:
---------------
echo htmlspecialchars("&");
echo htmlspecialchars("—");

Expected result:
----------------
&
—

Actual result:
--------------
&
—
