Description:

that is a small function however when i type ? ? ? ? ? it gives me the character ok i can even save it on to a mysql table fine.  but when i type ? it gives me a n i have tested it on many ways but i think that the get_text() function is giving me that error.

i use the php 5.2 and gtk 2.0.1 and older versions tested too

Reproduce code:
---------------
<?php
$window = new GtkWindow();
$window->set_size_request(400, 240);
$window->connect_simple('destroy', array('Gtk','main_quit'));
$window->add($vbox = new GtkVBox());

// display title
$title = new GtkLabel("setup entry");
$title->modify_font(new PangoFontDescription("Times New Roman Italic 10"));
$title->modify_fg(Gtk::STATE_NORMAL, GdkColor::parse("#0000ff"));
$title->set_size_request(-1, 40);
$vbox->pack_start($title, 0, 0);


$item_number = new GtkEntry();
$item_number->connect('insert-text', 'on_insert'); // note 1

$hbox = new GtkHBox();
$hbox->pack_start(new GtkLabel('Item Number: '), 0, 0);
$hbox->pack_start($item_number, 0, 0);
$vbox->pack_start($hbox);
$vbox->pack_start(new GtkLabel("Note: item numbers should contain only numbers 0 to 9"), 0, 0);

$window->show_all();
Gtk::main();

function on_insert($entry, $text, $len, $position) {
    $text = substr($text, 0, $len); // this is the new text inserted
    echo $text;
    return false; // yes, let the default handler display the number
}

?>

Expected result:
----------------
get_text show me the ?

Actual result:
--------------
shows a n
