渲染时捕获UnicodeEncodeError：'ascii'编解码器无法编码位置4-5中的字符：序数不在范围内（128）

你好，我住在波兰，所以我必须处理像łóźć等字母 . 当我尝试添加，在管理pannel，文本像“ZespółSzkół”我得到这样的错误：

渲染时捕获UnicodeEncodeError：'ascii'编解码器无法编码位置4-5中的字符：序数不在范围内（128）

我在Stackoverflow页面上看到很多类似的问题，但我不知道如何解决我的问题 .

我的数据库是 MySQL

我的数据库的Unicode集合： utf8_unicode_ci

我的 models.py

# -*- coding: utf-8 -*-
from django.db import models
import codecs

...    

class experience(models.Model):
    dateStart = models.DateField()
    dateEnd = models.DateField()
    company = models.CharField(max_length=50)
    position = models.CharField(max_length=50)
    description = models.TextField(max_length=255)
    def __unicode__(self):
        return self.company.decode('utf8')
