function isCharacterKeyPress(evt) {
    if (typeof evt.which == "undefined") {
        // This is IE, which only fires keypress events for printable keys
        return true;
    } else if (typeof evt.which == "number" && evt.which > 0) {
        // In other browsers except old versions of WebKit, evt.which is
        // only greater than zero if the keypress is a printable key.
        // We need to filter out backspace and ctrl/alt/meta key combinations
        return !evt.ctrlKey && !evt.metaKey && !evt.altKey && evt.which != 8;
    }
    return false;
}
