|

|
|
* 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 :

|
|

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