UnicodeDecodeError与JSON

我只是试图从我生成的哈希列表中生成一些JSON。下面是列表中的每个对象的样子：UnicodeDecodeError与JSON

{ 'name': unicode(name) }

下面是我在其序列：

import simplejson as json 

return HttpResponse(LazyEncoder().encode(output_list, ensure_ascii=False), mimetype="application/json") 

class LazyEncoder(json.JSONEncoder): 
    def default(self, obj): 
     if isinstance(obj, Promise): 
      return force_unicode(obj) 
     return super(LazyEncoder, self).default(obj)

推荐这懒散编码by the Django docs here.

这里是我得到的错误：

UnicodeDecodeError at /territories 
'ascii' codec can't decode byte 0xc3 in position 4: ordinal not in range(128)

为什么它试图编码为ascii即使我s特意问到不是？

请为错误提供更好的堆栈跟踪。 –

完成，stacktrace添加。 –
