I am trying to detect if a text input field has any character that doesn't belong to the GSM 7 bit alphabet. The table with the characters is here http://www.dreamfabric.com/sms/default_alphabet.html
After a lot of searching I found this (What regular expression do I need to check for some non-latin characters?) that its pretty close to what I want to accomplish because It detects Non latin characters. How can I alter the regular expression to include the GSM 7 bit alphabet?
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>test foreign chars</title>
</head>
<body>
<input id="foreign_characters" size="12" type="text" name="foreign_characters" value="test">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript">
(function(){
$('#foreign_characters').on("keyup", function(){
var foreignCharacters = $("#foreign_characters").val();
var rforeign = /[^u0000-u007f]/;
if (rforeign.test(foreignCharacters)) {
alert("This is non-Latin Characters");
} else {
alert("This is Latin Characters");
}
});
})();
</script>
</body>
</html>
