> What is the actual problem?
The problem is that the Tree is not rendered at all in I.E.
Now, the header of the JSON and the HTML page is UTF-8 encoded, before my last change, the JSON was iso-8859-1 and the HTML didn't have encoding type. The change I did doesn't solve the problem.
BTW, in Firefox it doesn't matter if the JSON has accented chars.
[Solved] Valid JSon for Internet Explorer
I replaced the UTF-8 encoder in the backend, and now it works like a charm!.
Thanks for your help,

Can you try it with IE8? Then you could debug it.
Thanks Animal, but Don't worry, now it's solved.
