我目前正在使用Django-countries获取表单字段的ISO国家/地区名称列表 . 它在我的网站上显示没有错误，但在Django的管理站点上，由于存在非ASCII国家/地区名称，它会导致上述错误：
Unicode错误提示：无法编码/解码的字符串是：itanÅland
我已经读过类似的问题可以通过 encode('utf-8') 属性来解决，但是如果不必触及Django Admin本身就不太可行 . 如果有人能解决这个问题，我将不胜感激 .

将此添加到您的模型：
并将此类的 str 方法更新为：
您还需要确保UserProfile的表示形式编码为
utf8试试这个:(你来自unicode字符串）我认为这可能是问题所在
