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.

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.

The line that triggered the error is a blank line (it stopped on line 66346).

This is what the relevant part of my script looks like:

log = open('/Users/Owner/Desktop/Exodus Logs/DIRTYLOGS/serverlog_20130430_00.15.21.txt', 'r') for line in log:

and the exception is:

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>

  • What encoding is the file in? Commented May 13, 2013 at 18:14
  • Strangly, This seems to only occured if I used specific file. It stopped at spefiic line as well. Commented May 13, 2013 at 18:14

    Your windows default encoding is cp1252 but the file is not using that encoding. Commented May 13, 2013 at 18:15

    @Bugboy1028 By definition, you cannot find an encoding in the decoded file itself. You always have to remember it alongside the file, or devise a detection scheme for your file format. Commented May 13, 2013 at 18:17

    you can try chardet to guess the encoding Commented May 13, 2013 at 18:20

Try:

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:

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

enc = 'iso-8859-15'

also try:

enc = 'cp437'

wich is very old but it also has the "ü" at 0x81 wich would fit to the string "üßer" wich I found on the homepage of assault cube.

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

The encoding parameter isn't available on Python 2
Rigth. For Python 2.x see stackoverflow.com/questions/10971033/…
In my case, I had a text file with Windows CRLF instead of Unix LF.
