在Python 3.10中读取CSV文件时看到的无效字符

Question

我正在从CSV文件中读取一些url，并只是在控制台中打印它们。当我打印时，我看到一些url的'-'在控制台中被'–'取代。

我的函数读取csv如下:

def read_dict_csv():
list_of_urls = []
try:
with open('csv/result.csv', 'r') as csv_file:
csv_reader = csv.reader(csv_file)
#next(csv_reader)
for line in csv_reader:
#print(line[0])
list_of_urls.append(line[0])
except FileNotFoundError as exp:
print(exp.strerror, exp.filename)
return list_of_urls

我的CSV文件如下:
