HI all,

When I apply a one trim callback via filter, I get an erroneous result on the display.

Sorry , i'm french...

Reproduce code:
---------------
$_SERVER['REMOTE_ADDR'] = '    80.10.20.30  ';

$remote_addr_list = explode(',', $_SERVER['REMOTE_ADDR']);
filter_var_array(array('remote_addr_list' => $remote_addr_list),
array('remote_addr_list' => array('filter' => FILTER_CALLBACK, 'options' => 'trim','flags'=> FILTER_REQUIRE_ARRAY|FILTER_FORCE_ARRAY)));

I has this result :

echo '<pre>';
print_r($remote_addr_list);
echo '</pre>';


Expected result:
----------------
Array
(
    [0] => 80.10.20.30
)

Actual result:
--------------
Array
(
    [0] => &#65533;&#65533;&#65533;)&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;
)
