UnicodeDecodeError: 'utf-8' codec can't decode byte

for line in open('u.item'): #read each line

whenever I run this code it gives the following error:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 2892: invalid continuation byte

I tried to solve this and add an extra parameter in open(), the code looks like;

for line in open('u.item', encoding='utf-8'): #read each line

But again it gives the same error. what should I do then! Please help.

 

解决方案：

As suggested by Mark Ransom, I found the right encoding for that problem.

The encoding was "ISO-8859-1", so replacing open("u.item", encoding="utf-8") with open('u.item', encoding = "ISO-8859-1") will solve the problem.
