Problem with encoding in jquery

Hi. I have next problem.
There are files core.js and test.js
There is a function in core.js file, that shows error text.

//core.js
function showError(text) {
    $('#alertPlace').html('<div class="alert alert-danger"><button type="button" class="close" data-dismiss="alert">×</button>' + text + '</div>');
}

somewhere on my page there is an empty div, where the error message should be displayed:

...
<div id="alertPlace"></div>
...

and in my test.js file i call showError function.

...
showError("Заполните все поля."); //input all fields
...

so, when i want to display russian text, i get ????? (��������� ��� ����) symbols, instead of text. when i display english text, all is fine.

P.S. i include core.js and test.js in my html page. also i set there

<meta charset="utf-8" />

Any ideas?
