IE again excelled or wrong encoding in NodeJS?

Question

Node.js

The point is. There is a NodeJS get method that takes the name of the server as input and checks it for availability by parameters.

app.get('/addserver', function(request, response) {
  var $set = {};
        $set[request.query.server] = {"available":true, "token":request.query.accesskey};
        validator.check($set).done(function(){
    response.send('OK!');
    response.end();
        }).fail(function(e){
    response.send(e);
    response.end();
        });
});

Of all tested browsers (Chrome, Opera, Firefox, Safari) request.query.server is passed perfectly in the right encoding (UTF8) and only IE passes "����224". How to overcome this nightmare?
UPD. Request example:
