如何比较两个包含变音字符的UTF-8字符串

我想添加一个像这个小提琴的元素,但是当字符串具有UTF-8字符时,我有一个问题来比较我的字符串,因为"é" is > at all basics letters.

$(".ingredient").click(function() {
    var element = $(this);
    var added = false;
    var targetList = $(this).parent().siblings(".ingredientList")[0];
    $(this).fadeOut("fast", function() {
        $(".ingredient", targetList).each(function() {
            if ($(this).text() > $(element).text()) {
                $(element).insertBefore($(this)).fadeIn("fast");
                added = true;
                return false;
            }
        });
        if (!added) $(element).appendTo($(targetList)).fadeIn("fast");
    });
});

$(".ingredient").click(function() {
    var $element = $(this);
    var $targetList = $element.closest('.ingredientList').siblings().first();

    $element.fadeOut("fast", function() {
        $element.appendTo($targetList);    
        $(".ingredient", $targetList).sort(function(a, b) {
            return $(a).text().localeCompare($(b).text());
        }).appendTo($targetList);
        $element.fadeIn('fast');
    });
});
