Answer 3

alert("4-12\u4e2a\u82f1\u6587\u5b57\u6bcd\u3001\u6570\u5b57\u548c\u4e0b\u5212\u7ebf");

Answer 4

var hexToDec = function(str) {
    str=str.replace(/\\/g,"%");
    return unescape(str);
}
alert(hexToDec("\u8bf7\u518d\u786e\u8ba4\u4e00"));

Answer 5

\un 匹配 n，其中 n 是一个用四个十六进制数字表示的 Unicode 字符。例如， \u00A9 匹配版权符号 (?)。
例如："4-12\u4e2a\u82f1\u6587\u5b57\u6bcd\u3001\u6570\u5b57\u548c\u4e0b\u5212\u7ebf"
页面是可以直接解释的，无需任何转换
4-12个英文字母、数字和下划线如果想从中文得到类似结果，可以用 escape，然后将 % 号替换为 \ 即可！
document.write(escape("4-12个英文字母、数字和下划线"));
//4-12%u4E2A%u82F1%u6587%u5B57%u6BCD%u3001%u6570%u5B57%u548C%u4E0B%u5212%u7EBF
