     * cf https://developer.mozilla.org/En/XMLHttpRequest/Using_XMLHttpRequest#Receiving_binary_data_in_older_browsers
     * In IE <= 9, we must use (the IE only) attribute responseBody
     * (for binary data, its content is different from responseText).
     * In IE 10, the 'charset=x-user-defined' trick doesn't work, only the
     * responseType will work :
