Description:
------------
Array which mb_convert_variables does not specify is 
changed.

I think that this operation is not specification but 
a bug with it being individual.

Isn't it changed about this operation by PHP4.3.5 or 
it or later?


Reproduce code:
---------------
<?
// no problem.
$Str1  = "multi-byte string's";
$Str2 = $Str1;

mb_convert_variables( "SJIS",
                      mb_detect_order( ),
                      $Str2 );
var_dump( $Str1 );
var_dump( $Str2 );

// unexpected operation.
$Array1  = array( "multi-byte string's" );
$Array2  = $Array1;

mb_convert_variables( "SJIS",
                      mb_detect_order( ),
                      $Array2 );
var_dump( $Array1 );
var_dump( $Array2 );
?>


Expected result:
----------------
string(4) "no changed multi-byte string's"
string(3) "changed multi-byte string's"
array(1) {
  [0]=>
  string(3) "no changed multi-byte string's"
}
array(1) {
  [0]=>
  string(3) "changed multi-byte string's"
}


Actual result:
--------------
string(4) "no changed multi-byte string's"
string(3) "changed multi-byte string's"
array(1) {
  [0]=>
  string(4) "no changed multi-byte string's"
}
array(1) {
  [0]=>
  string(3) "changed multi-byte string's"
}

string(4) "no changed multi-byte string's"
string(3) "changed multi-byte string's"
array(1) {
  [0]=>
  string(3) "changed multi-byte string's"
}
array(1) {
  [0]=>
  string(3) "changed multi-byte string's"
}
