Description:
------------
when decoding named entities with html_entity_decode, the resulting characters are sometimes incorrect. e.g., "€" becomes the UTF-8 representation of the ⁄ entity (fraction slash). not all entities are incorrectly translated, though. numerical entities work correctly.

tested with both php-5.0.0RC3 and the proposed -RC4 from snaps.php.net/~andi/

config :

./configure  --with-apxs=/usr/bin/apxs --with-mysql=/usr/local/mysql --with-gd --enable-safe-mode --with-dom=/usr --enable-ftp --with-zlib --with-xsl --with-xmlrpc --enable-cli --enable-bcmath --with-iconv --with-jpeg-dir=/usr --with-png-dir=/usr --with-xpm-dir=/usr/X11R6



Reproduce code:
---------------
// all tests are viewed with browser encoding forced on UTF-8.
<?php
  print html_entity_decode("&euro;",ENT_NOQUOTES,"UTF-8");
  print "<br />";
  print htmlentities(html_entity_decode("&euro;",ENT_NOQUOTES,"UTF-8"),ENT_NOQUOTES,"UTF-8");
?>

// other test also available on 
// http://fire.desk.nl/decode/index.php
// (just enter &euro; and submit)
// and http://fire.desk.nl/decode/index.phps (source)

Expected result:
----------------
a euro-sign
a euro-sign


Actual result:
--------------
a fractional slash
a euro-sign
