unicode和gbk的互相转换

unicode和gbk的互相转换主要依靠window下的escape和unescape方法,然后把%u替换成u就好了;

var GB2312UnicodeConverter = {
    ToUnicode: function (str) {
        return escape(str).toLocaleLowerCase().replace(/%u/gi, '\u');
    }
    , ToGB2312: function (str) {
        return unescape(str.replace(/\u/gi, '%u'));
    }
}; 

easy to understand!~.~
