当解码使用默认的 decode() 拨错时，可以设置 errors 参数的值来解决

print(line)
line_de_replace = line.decode(errors='replace').strip()  # 用？代替
print("line_de_replace:", line_de_replace)
line_de_ignore = line.decode(errors='ignore').strip()  # 直接去除
print("line_de_ignore:", line_de_ignore)
line_de_backslashreplace = line.decode(errors='backslashreplace').strip()  # 加 \ 转义 
print("line_de_backslashreplace:", line_de_backslashreplace)
# line_de_strict = line.decode(errors='strict')  # 默认设置，会报错
# print("line_de_strict:", line_de_strict)
