我收到此错误：

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2026' in position 551: ordinal not in range(128)

我试图通过使用不同的编码定义来解决这个问题，甚至使用utf-8编码将数据帧写回到csv。

我该怎么办？

from textblob import TextBlob
import pandas as pd
path = 'Tweets.csv'
df = pd.read_csv(path, delimiter=',', header='infer')
df.to_csv('tweets_encoded.csv', encoding='utf-8')
df = pd.read_csv('tweets_encoded.csv', delimiter=',', header='infer', encoding='utf-8"')

我尝试使用chardet查找编码

rawdata=open('Tweets.csv',"r").read()
chardet.detect(rawdata)
{'confidence': 0.5471323391929904,
 'encoding': 'Windows-1254',
 'language': 'Turkish'}

运行时出现错误

x =  df[['text']]
x['subjectivity'] = df.text.apply(lambda x: TextBlob(str(df[['text']])).sentiment.subjectivity)
df.head()

UnicodeDecodeError：'ascii'-解决方法
