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

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

    I have forked billy's code http://jsfiddle.net/billybraga/UHmnf/ (from his post) into this: http://jsfiddle.net/infralabs/dJX58/

    I corrected transcription of ſ and ß characters and also added coversion of these ones: Þþ, Ðð, Ŋŋ, IJij, Œœ.

    The modified snippet is below:

    Shortened code based on the excellent solution by Ian Elliott:

    accentsTidy = function(s){
        var r = s.toLowerCase();
        non_asciis = {'a': '[àáâãäå]', 'ae': 'æ', 'c': 'ç', 'e': '[èéêë]', 'i': '[ìíîï]', 'n': 'ñ', 'o': '[òóôõö]', 'oe': 'œ', 'u': '[ùúûűü]', 'y': '[ýÿ]'};
        for (i in non_asciis) { r = r.replace(new RegExp(non_asciis[i], 'g'), i); }
        return r;
    };
    

    Edit: Corrected non-working code

    Here's a very simple solution without too much code using a very simple map of diacritics that includes some or all that map to ascii equivalents containing more than one character, i.e. Æ => AE, ffi => ffi, etc... Also included some very basic functional tests

    var diacriticsMap = {
      '\u00C0': 'A',  // À => A
      '\u00C1': 'A',   // Á => A
      '\u00C2': 'A',   // Â => A
      '\u00C3': 'A',   // Ã => A
      '\u00C4': 'A',   // Ä => A
      '\u00C5': 'A',   // Å => A
      '\u00C6': 'AE', // Æ => AE
      '\u00C7': 'C',   // Ç => C
      '\u00C8': 'E',   // È => E

    I used string.js's latinise() method, which lets you do it like this:

    var output = S(input).latinise().toString();
