[XeTeX] Hebrew in Xetex

[Erwin Ochsenmeier]

I am trying to write RtL Hebrew in XeTeX (XeTeXk, Version  
3.141592-2.2-0.996 (Web2C 7.5.6)) using TexShop. Everything works  
fine, except the Hebrew diacritic signs do not display properly using  
SBL Hebrew but work fine using Cardo. This the preamble

%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode

\documentclass[12pt]{article}
\TeXXeTstate=1
\usepackage{fontspec}

%\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\defaultfontfeatures{Scale=MatchLowercase}
\setromanfont{Hoefler Text}
\setmonofont[Scale=0.90,Ligatures=NoCommon]{Courier}

\font\C = ''Cardo'' at 16 pt
\font\H = ''SBLHebrew'' at 16 pt

\title{}
\date{}

\begin{document}
\maketitle

This is the result. Any idea what the problem might be?
