pathinfo() function returns invalid "filename" array part for utf-8 filename

Reproduce code:

$utf8str = "&#1055;&#1056;&#1048;&#1042;&#1045;&#1058;_&#1052;&#1045;&#1044;&#1042;&#1045;&#1044;.mp4";
$path = pathinfo($utf8str);



Expected result:
string(25) "&#1055;&#1056;&#1048;&#1042;&#1045;&#1058;_&#1052;&#1045;&#1044;&#1042;&#1045;&#1044;" 

Actual result:
string(13) "_&#1052;&#1045;&#1044;&#1042;&#1045;&#1044;"

utf-8 strings i submitid there got replaced by entities :( The main thing is there should be a "_" sign in filename. Then "filename" part becomes splitted by it. If there is no "_" sign, the "filename" part is empty.

Please provide a proper test case. I tested this on command line and 
it works just fine. (check your charset settings..)

Can confirm on Linux with PHP 5.2.9

var_dump(pathinfo("foobar.ext", PATHINFO_FILENAME)); // string(6) "foobar"
var_dump(pathinfo("f&#337;oobar.ext", PATHINFO_FILENAME)); //string(8) "főoobar"
var_dump(pathinfo("&#337;oobar.ext", PATHINFO_FILENAME)); //string(5) "oobar"

This works well in CLI mode!
