在一次使用Python操作大量文件的过程中，出现了“'utf-8' codec can't decode bytes in position 924-925”编码问题，于是上网搜索，发现一个靠谱的答案：
“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.”
