Remove accents/diacritics in a string in JavaScript

Question

How do I remove accentuated characters from a string? Especially in IE6, I had something like this:

accentsTidy = function(s){
    var r=s.toLowerCase();
           


        

Answer 1

One solution that seems to be way faster by the given test : http://jsperf.com/diacritics/9

function removeDiacritics(str) {
   return str.replace(/[^A-Za-z0-9\s]+/g, function(a){
      return diacriticsMap[a] || a; 
   });
}
removeDiacritics(teste);

Working example: http://jsbin.com/sovorute/1/edit

Reasoning: One reason this is much faster is because we only iterate through the special characters, picked by the negated regex pattern. The fastest of the tests (String Iteration without in) iterates 1001 on the given text, which means every character. This one iterates only 35 times and outputs the same result. Keep in mind that this will only replace what is indicated in the map.
