Hello,

For a WebGL application, I need to be able to parse a binary encoded file. The basic Ajax request response is a Unicode string with data loss (multiple byte combinations can produce the same non-valid unicode character). An option is available to the XMLHttpRequest component to allow this binary transfer. We just need to add this line:

req.overrideMimeType('text/plain; charset=x-user-defined');

You can read more about this technique at the Mozilla Developer Center: https://developer.mozilla.org/En/Using_XMLHttpRequest#Receiving_binary_data

It doesn't work on all browsers and I couldn't find any workaround for unsupported browsers.

• Chrome 4.0.295.0: Works
• Firefox 3.5.7: Works
• Safari 4.0.4: Works
• Internet Explorer 8: Does not work. Doesn't have the overrideMimeType method.
• Opera 10.10: Does not work. Have the overrideMimeType method but doesn't take it in account.
