问一个javascript \u的显示问题

<script language="javascript">
var ww = "\u00e7\u00e8";
alert(ww);
</script>

我需要下面这样的写法，然后和上面输出的结果相同。。

<script language="javascript">
var ac = "e7";

var ad = "u00" + ac;
var ae = "\"\\" + ad + "\"";

alert(eval(ae));
</script>


现在又多了ad = "e8"; ,af = "e9"; 等等
我有不会写了。。。

---

var ac = "e7";
var ad = "e8";

ae = "\"\\" + ac + "\"";
af = "\"\\" + ad + "\"";
ae += af;
alert(eval(ae));

我这样写没成功。。。

---

var ac = "u00" +"e7";
var ad = "u00" +"e8";

ae = "\"\\" + ac + "\"";
af = "\"\\" + ad + "\"";
ae += af;
alert(eval(ae));

我这样写没成功。。。
