AngularJS `removeAccents` filter

remove-accents.js

angular.module('utils.filters', [])
.filter('removeAccents', removeAccents);

function removeAccents() {
    return function (source) {
        var accent = [
            /[\300-\306]/g, /[\340-\346]/g, // A, a
            /[\310-\313]/g, /[\350-\353]/g, // E, e
            /[\314-\317]/g, /[\354-\357]/g, // I, i
            /[\322-\330]/g, /[\362-\370]/g, // O, o
            /[\331-\334]/g, /[\371-\374]/g, // U, u
            /[\321]/g, /[\361]/g, // N, n
            /[\307]/g, /[\347]/g, // C, c
        ],
        noaccent = ['A','a','E','e','I','i','O','o','U','u','N','n','C','c'];

        for (var i = 0; i < accent.length; i++){
            source = source.replace(accent[i], noaccent[i]);
        }

        return source;
    };
} // removeAccents

It should not remove accents in the result but only when filtering
