Fuzzy icon in messageBoxInfo

[N6REJ]

trafficstars

We're using a BOX_INFO to show a message box with a ! inside of it. It's coming out rather ragged around the edges. Is there anyway to clean this up or perhaps use a Font Awesome icon instead?

    /**
     * Displays an informational message box.
     *
     * @param   string       $message  The message to display.
     * @param   string|null  $title    The title of the message box.
     *
     * @return mixed The result of the message box operation.
     */
    public function messageBoxInfo($message, $title = null)
    {
        return $this->messageBox($message, self::BOX_INFO, $title);
    }
