The way i found to writw text in hebrew going this way:
1. look at this image and copy to your dialoge box



2. Open the "page html" and inset this lines between head tag:
<STYLE type=text/css>DIV#container {direction: rtl;
MARGIN-TOP: 0px; MARGIN-LEFT: auto; WIDTH: 1000px; MARGIN-RIGHT: auto; POSITION: relative; TEXT-ALIGN: left
}
you can see it here:


Now it should work.
