While reading file on Python, I got a UnicodeDecodeError. What can I do to resolve this?
提问by Bugboy1028
This is one of my own projects. This will later help benefit other people in a game I am playing (AssaultCube). Its purpose is to break down the log file and make it easier for users to read.
这是我自己的项目之一。这将有助于在我正在玩的游戏（AssaultCube）中让其他人受益。其目的是分解日志文件，方便用户阅读。
I kept getting this issue. Anyone know how to fix this? Currently, I am not planning to write/create the file. I just want this error to be fixed.
我一直收到这个问题。有人知道怎么修这个东西吗？目前，我不打算编写/创建文件。我只想修复这个错误。
The line that triggered the error is a blank line (it stopped on line 66346).
触发错误的行是一个空行（它停在第 66346 行）。
This is what the relevant part of my script looks like:
这是我脚本的相关部分的样子：
log = open('/Users/Owner/Desktop/Exodus Logs/DIRTYLOGS/serverlog_20130430_00.15.21.txt', 'r')
for line in log:
and the exception is:
例外是：
Traceback (most recent call last):
File "C:\Users\Owner\Desktop\Exodus Logs\Log File Translater.py", line 159, in <module>
main()
File "C:\Users\Owner\Desktop\Exodus Logs\Log File Translater.py", line 7, in main
for line in log:
File "C:\Python32\lib\encodings\cp1252.py", line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 3074: character maps to <undefined>

Try:
尝试：
enc = 'utf-8'
log = open('/Users/Owner/Desktop/Exodus Logs/DIRTYLOGS/serverlog_20130430_00.15.21.txt', 'r', encoding=enc)
if it won't work try:
如果它不起作用尝试：
enc = 'utf-16'
log = open('/Users/Owner/Desktop/Exodus Logs/DIRTYLOGS/serverlog_20130430_00.15.21.txt', 'r', encoding=enc)
you could also try it with
你也可以试试
enc = 'iso-8859-15'
also try:
也可以尝试：
enc = 'cp437'
wich is very old but it also has the "ü" at 0x81 wich would fit to the string "ü?er" wich I found on the homepage of assault cube.
这是非常古老的，但它在 0x81 处也有“ü”，这将适合我在攻击立方体的主页上找到的字符串“ü?er”。
If all the codings are wrong try to contact some of the guys developing assault cube or as mentioned in a comment: have a look at https://pypi.python.org/pypi/chardet
如果所有编码都错误，请尝试联系一些开发攻击立方体的人或如评论中所述：查看https://pypi.python.org/pypi/chardet
