Django模板上的Unicode字符串显示

我正在使用django v1.5.*，我将渲染一个名为"foobar"的变量，该变量是json obj，包括unicode字符串.

I am using django v1.5.*, I am going to render the a variable named "foobar" which is a json obj and including unicode string.

def home( request ):
    import json
    foo = {"name": u"赞我们一下"}
    bar = json.dumps( foo )
    return render_to_response( 'myapp/home.html',
        { "foobar": bar, },
        context_instance=RequestContext(request)
    )

在我的模板中，我用javascript编码json obj，然后追加到div，它可以显示预期的字符串:

And in my template, I encode the json obj in javascript and then append to the div, it can display the expected string:

  foobar=JSON.encode('{{foobar|safe}}'); 
  $("#foobar").html(foobar.name);`

然后我可以在网页上获取赞一下我们.
但是我发现如果直接使用变量:

then I can get the 赞一下我们 on my web page.
But I found that if I use the variable directly:

<div id="foobar">{{ foobar }}</div>

它将unicode字符串显示为字节字符串:
{ "name":"\u8d5e\u4e00\u4e0b\u6211\u4eec" }
即使我使用{{foobar|safe}}，也没有任何改变.

it will display the unicode string as byte string:
{ "name":"\u8d5e\u4e00\u4e0b\u6211\u4eec" }
Even if I using the {{foobar|safe}} then nothing change.

现在，我想问为什么会发生这种情况，或者我有什么毛病?如果我想直接将变量用作{{ foobar }}怎么办?

Now, I want to ask why this happend or is anything wrong of me? What should I do if I do want to using the variable directly as {{ foobar }} ?
