本文介绍了UnicodeEncodeError：'ascii'编解码器不能在35位编码字符u'\xc5'：ordinal不在范围（128）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我目前正在使用 Django-countries 获取表单的ISO国家/地区名单领域。在我的网站上显示没有错误，但在Django的管理网站上，由于存在非ASCII国家/地区名称，导致上述错误：
I am currently using Django-countries to get a list of ISO country names for a form field. It displays without error on my website, but on Django's Admin site it causes the aforementioned error due to the presence of non-ASCII country names:
Unicode error hint: The string that could not be encoded/decoded was: itan Åland
我已经看到类似的问题可以使用 encode（'utf-8'）属性进行结算，但是如果不必触摸Django管理员本身，这似乎不太可行。如果有人有这个问题的解决方案，我会非常感激。
I've read that similar problems can be settled with the encode('utf-8') attribute, but this does not seem very feasible without having to touch Django Admin itself. I would greatly appreciate it if anyone has a solution to this problem.

Exception Value: 'ascii' codec can't encode character u'\xc5' in position 35: ordinal not in range(128)
推荐答案
尝试这个：（u来自unicode字符串）我认为这可能是问题
try this: (u"" from unicode strings) i think it might be the problem
def __str__(self):
return u"{0} by {1}".format(self.tour_name, self.tour_guide)
这篇关于UnicodeEncodeError：'ascii'编解码器不能在35位编码字符u'\xc5'：ordinal不在范围（128）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
