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

64     * I'd like to use jQuery to avoid this XHR madness, but it doesn't support
65     * the responseType attribute : http://bugs.jquery.com/ticket/11461
