I guess this is it.
The Python program in Windows cannot read UTF-8 text files

Python text file input/output on Windows is set to AnsiCodePage (shift JIS=cp932) by default.
The article around here also shows how to deal with situations and environmental variables.

Unicode HOWTO

However, encoding will still be mixed, so encoding for each file should be specified.

Also note that using common features such as python.py or test or the name of the module you are trying to load can cause problems.It's good to search and remember the common mistakes of beginners
