When you write non-ASCII characters directly into your page source, you need to 
make sure you use a meta tag to set the charset. To see the difference it 
causes, consider these two sources below.

/* No META charset */
<script type="text/javascript" 
src="http://crypto-js.googlecode.com/files/2.0.0-crypto-sha256.js"></script>
<script type="text/javascript">
var m = "á";
alert(m.length); // alerts 2
alert(Crypto.SHA256(m)); // alerts

</script>

/* Has META charset */
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" 
src="http://crypto-js.googlecode.com/files/2.0.0-crypto-sha256.js"></script>
<script type="text/javascript">
var m = "á";
alert(m.length); // alerts 1
alert(Crypto.SHA256(m)); // alerts
