endcoding error

my code has a trouble with encoding error:

File "test.py", line 1

SyntaxError: encoding problem: with BOM

I attached the code below. is there any clear idea to fix it? the input and the output file contain Korean words, numbers, and english charaters.

I try to run this code in Mac and windows, it doesn't work at both of OS. please help me out!

You've misspelled UTF-8 on the first line. Since you've only used ASCII characters in you're code, it isn't even required to have a coding line.

The problem is not with the code, but with the encoding of the script itself. Try saving it with a different editor. Notepad on Windows works for me.
