What's wrong with my regular expressions?

I want to check my fileName which can be 2013_09_北京.doc or 2013_09_广东_1.doc or 2013_09_中国人_anywords.doc,but I find that 2013_09_北京.doc is checked OK,but 2013_09_广东_1.doc seems wrong,what's wrong with my codes?

 // fileName='2013_09_北京.doc'；// right
 fileName='2013_09_北京_1.doc'；// wrong
var patt1 = new RegExp("^2013_(0[1-9]|1[0-2])_([\\u4e00-\\u9fa5]{2,3})(_[\S]*)?\.(doc)$");
        if (!patt1.test(fileName)) {
         alert('input format like 2013_09_北京.doc或2013_09_北京_1.doc’);
        }
        else
        alert('right format!');

You did not escape \S and \. in your string, this should fix it:

var patt1 = new RegExp("^2013_(0[1-9]|1[0-2])_([\\u4e00-\\u9fa5]{2,3})(_[\\S]*)?\\.(doc)$");
