adding new letters to memberlist.php

[ohadpartuck]

hi.
I am trying to enable search by my own language letters in the http://www.s-maof.com/Forum/memberlist.php .
so i added this code to memberlist.php at line 504


The thing is that my letters are in hebrew.
The code seems to have problems with that

PHP Code:

for ($i=128; $i < 154; $i++)
    {
        //$currentletter = $i;
        $currentletter = chr($i);
        $linkletter =& $currentletter;
        $show['selectedletter'] = $selectedletter == $currentletter ? true : false;
        $templater = vB_Template::create('memberlist_letter');
            $templater->register('currentletter', $currentletter);
            $templater->register('linkletter', $linkletter);
            $templater->register('ltrurl', $ltrurl);
            $templater->register('perpage', $perpage);
            $templater->register('sortfield', $sortfield);
            $templater->register('sortorder', $sortorder);
            $templater->register('usergrouplink', $usergrouplink);
        $letterbits .= $templater->render();
    } 


which is the same for the english letters but just different ascii values.
the thing is the code in line 350

PHP Code:

$condition .= " AND username LIKE(\"" . $db->escape_string_like($ltr) . "%\")"; 


doesn't search for the right letter. This is a coding problem.
The advanced serach in my language works. I just don't know how does it do it..!
