UnicodeEncodeError:'ascii'编解码器无法编码1-4位的字符:序号不在范围内(128)

Question

我看到很多与此相关的问题,但我无法找出解决方案.

这是在Django 1.4和Python 2.7上.

data是一个包含UTF8字符的字典.看到这一行:

render_to_response('application/app.html', data, context_instance=RequestContext(request))

获取模板以从中输出值data.

为什么它会爆炸,我该怎么做才能解决这个问题？

编辑:挖掘后,其中一部分data包含lxml.objectify.ObjectifiedElement.基本上是一个可以像普通字典一样查询的XML元素.它产生的值似乎是正确的unicode字符串,如下所示:u'\xae\u2020\xa5\xa8\u02c6\xf8'

这是完整的堆栈跟踪:

UnicodeEncodeError: 'ascii' codec can't encode characters in position 1-4: ordinal not in range(128)

Answer 1

它不应包含UTF-8 字符；它应该包含unicodes。

{'foo': u'bar'}
