Efficiently replace all accented characters in a string?

Question

For a poor man\'s implementation of near-collation-correct sorting on the client side I need a JavaScript function that does efficient single character rep

The complete solution to your request is:

function convert_accented_characters(str){
    var conversions = new Object();
    conversions['ae'] = 'ä|æ|ǽ';
    conversions['oe'] = 'ö|œ';
    conversions['ue'] = 'ü';
    conversions['Ae'] = 'Ä';
    conversions['Ue'] = 'Ü';
    conversions['Oe'] = 'Ö';
    conversions['A'] = 'À|Á|Â|Ã|Ä|Å|Ǻ|Ā|Ă|Ą|Ǎ';
    conversions['a'] = 'à|á|â|ã|å|ǻ|ā|ă|ą|ǎ|ª';
    conversions['C'] = 'Ç|Ć|Ĉ|Ċ|Č';
    conversions['c'] = 'ç|ć|ĉ|ċ|č';
    conversions['D'] = 'Ð|Ď|Đ';
    conversions['d'] = 'ð|ď|đ';
    conversions['E'] = 'È|É|Ê|Ë|Ē|Ĕ|Ė|Ę|Ě';
    conversions['e'] = 'è|é|ê|ë|ē|ĕ|ė|ę|ě';
    conversions['G'] = 'Ĝ|Ğ|Ġ|Ģ';
    conversions['g'] = 'ĝ|ğ|ġ|ģ';
    conversions['H'] = 'Ĥ|Ħ';
    conversions['h'] = 'ĥ|ħ';
    conversions['I'] = 'Ì|Í|Î|Ï|Ĩ|Ī|Ĭ|Ǐ|Į|İ';
    conversions['i'] = 'ì|í|î|ï|ĩ|ī|ĭ|ǐ|į|ı';
    conversions['J'] = 'Ĵ';
    conversions['j'] = 'ĵ';
    conversions['K'] = 'Ķ';
    conversions['k'] = 'ķ';
    conversions['L'] = 'Ĺ|Ļ|Ľ|Ŀ|Ł';
    conversions['l'] = 'ĺ|ļ|ľ|ŀ|ł';
    conversions['N'] = 'Ñ|Ń|Ņ|Ň';
    conversions['n'] = 'ñ|ń|ņ|ň|ʼn';
    conversions['O'] = 'Ò|Ó|Ô|Õ|Ō|Ŏ|Ǒ|Ő|Ơ|Ø|Ǿ';
    conversions['o'] = 'ò|ó|ô|õ|ō|ŏ|ǒ|ő|ơ|ø|ǿ|º';
    conversions['R'] = 'Ŕ|Ŗ|Ř';
    conversions['r'] = 'ŕ|ŗ|ř';
    conversions['S'] = 'Ś|Ŝ|Ş|Š';
    conversions['s'] = 'ś|ŝ|ş|š|ſ';
    conversions['T'] = 'Ţ|Ť|Ŧ';
    conversions['t'] = 'ţ|ť|ŧ';
    conversions['U'] = 'Ù|Ú|Û|Ũ|Ū|Ŭ|Ů|Ű|Ų|Ư|Ǔ|Ǖ|Ǘ|Ǚ|Ǜ';
    conversions['u'] = 'ù|ú|û|ũ|ū|ŭ|ů|ű|ų|ư|ǔ|ǖ|ǘ|ǚ|ǜ';
    conversions['Y'] = 'Ý|Ÿ|Ŷ';
    conversions['y'] = 'ý|ÿ|ŷ';
    conversions['W'] = 'Ŵ';
    conversions['w'] = 'ŵ';
    conversions['Z'] = 'Ź|Ż|Ž';
    conversions['z'] = 'ź|ż|ž';
    conversions['AE'] = 'Æ|Ǽ';
    conversions['ss'] = 'ß';
    conversions['IJ'] = 'IJ';
    conversions['ij'] = 'ij';
    conversions['OE'] = 'Œ';
    conversions['f'] = 'ƒ';
    for(var i in conversions){
        var re = new RegExp(conversions[i],"g");
        str = str.replace(re,i);
    }
    return str;
}
