Convert from English Digits to Arabic ones in html page

Question

I need to convert all English numbers that appear in a given HTML page to Arabic ones (to be independent from the user browser encoding). I prefer to use javascript or it will be great if this can be handled using CSS.

I found some pages doing this but I found that the Arabic letters are added with their ASCII representation in the source code. Does it mean that they are applying some sort of a java script function?

Any clue how can I do something like this?

Answer 1

How about a straight replace function?

String.prototype.toIndiaDigits= function(){
 var id= ['۰','۱','۲','۳','۴','۵','۶','۷','۸','۹'];
 return this.replace(/[0-9]/g, function(w){
  return id[+w]
 });
}

// test

var S='The year 2009 has only 365 days';
alert(S.toIndiaDigits());

/*  returned value: (String)
The year ۲۰۰۹ has only ۳۶۵ days
*/
