UnicodeDecodeError：“ utf-8”编解码器无法解码位置1的字节0xb3：无效的起始字节

Question

我有选择特定词形式csv的代码，并创建了另一个包含该词的csv文件。

我已经通过将某些编码样式从utf-8更改为utf-16来更改了一些代码，但是都无法使用。

#-*- coding:utf-8-*-
import csv

input_filename = '/Users/chanhee.kang/Desktop/exit.csv'
output_filename = '/Users/chanhee.kang/Desktop/exit_mefge.csv'
reader = csv.reader(open(input_filename, 'r', encoding='utf-8'), delimiter=';')

input_header = next(reader)
columns_to_keep = []
for i, name in enumerate(input_header):
    if 'startup' in name:
        columns_to_keep.append(i)

writer = csv.writer(open(output_filename, 'w'), delimiter=';')
output_header = []
for column_index in columns_to_keep:
    output_header.append(input_header[column_index])

writer.writerow(output_header)

for row in reader:
    new_row = []
    for column_index in columns_to_keep:
        new_row.append(row[column_index])
    writer.writerow(new_row)

这些是以下错误：

    input_header = next(reader)
  File "/Users/chanhee.kang/anaconda3/lib/python3.7/codecs.py", line 322, in decode
