I’m not quite sure what you’re asking, but I’m going to assume you want to get the character associated with typing in a cyrillic character on a keyboard. If so, I imagine you’re using the wrong event (keydown or keyup) when the correct event is keypress. keydown and keyup tell you about the physical key pressed while keypress tells you about the character that was typed. Here’s a simple cross-browser example of how to get the typed character:

document.onkeypress = function(e) {
    e = e || window.event;
    var charCode = (typeof e.which == "number") ? e.which : e.keyCode;
    var typedChar = String.fromCharCode(charCode);
    alert("Typed character: " + typedChar);
};
