＆＃39;字符表＆＃39;编解码器不能解码6784位的字节0x90：字符映射到<undefined>

Question

我有一个包含100条推文的csv文件。我想处理这些推文中的每一个。所以，我写这段代码

import csv
with open('abctweets.csv',) as csvfile:
    reader = csv.DictReader(csvfile)
    count=0
    for row in reader:
        string = row['text']
        count=count+1
        print(count)

但在处理了578条推文后，它会抛出以下错误： -

return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 6784: character maps to <undefined>

根据答案我修改了代码

import csv with open('J_tsar_tweets.csv', encoding="utf8") as csvfile:
    reader = csv.DictReader(csvfile)
    count=0
    for row in reader:
        string = row['text']
        count=count+1
        print(count)

但是它甚至不处理578条推文并抛出错误：   （结果，消费）=
