String.prototype.toUnicode = function(){
    var result = "";
    for(var i = 0; i < this.length; i++){
        // Assumption: all characters are < 0xffff
        result += "\\u" + ("000" + this[i].charCodeAt(0).toString(16)).substr(-4);
    }
    return result;
};

a = 'Água' // COMBINING ACUTE ACCENT (A%CC%81gua)
b = 'Água' // LATIN CAPITAL LETTER A WITH ACUTE

c = a.normalize()
d = b.normalize()

c == d
// true
a == b
// false
