js中如何进行base64编码

Question

如下是base64编码：
var str_base64 = "CgkJCgkJCQk8Y29uZGl0aW9ucyB0eXBlPSJBTkQiPgoJCQkJCTxzeXNDb25kaXRpb25zIHR5cGU9Inx8Ij4KCQkJCQk8c3lzQ29uZGl0aW9uIG5hbWU9ItDCzsS1tSIgZXhwcmVzc2lvbj0iS0dselRtVjNSRzlqS0NrcElBPT0iLz4KCQkJCQk8c3lzQ29uZGl0aW9uIG5hbWU9IrWxx7C0psDtyMsiIGV4cHJlc3Npb249IktHbHpRM1Z5VlhObGNpZ3BLU0E9Ii8+CgkJCQkJPC9zeXNDb25kaXRpb25zPgoJCQkJPC9jb25kaXRpb25zPgoJCQk=";

项目引入了[base64.js][1]
var str = Base64.decode(str_base64 ); 
console.log(str);

输出内容如下：(**name中文乱码**)
//<conditions type="AND">
//    <sysConditions type="||">
//        <sysCondition name="ÐÂÎĵµ" expression="KGlzTmV3RG9jKCkpIA=="/>
//        <sysCondition name="µ±ǰ´¦ÀíÈË" expression="KGlzQ3VyVXNlcigpKSA="/>
//    </sysConditions>
//</conditions>

怎么通过js解决乱码问题??? Thanks

使用UTF8编码源信息吧
