title: python error "non-UTF-8 code starting with '\xe9' " when trying to compile
body: <p>I made this small code to pop up a windows message:</p>
  
  <pre><code>#-*- coding:Utf-8 -*-
  import ctypes
  ctypes.windll.user32.MessageBoxW(None, u"This file is not supported by your current version of Windows", u"Windows Error Message", 
  </code></pre>
  
  <p>It works well , but when I try to compile it with "pyinstaller errormessage.py", I get this error : </p>
  
  <pre><code>SyntaxError: Non-UTF-8 code starting with '\xe9' in file C:\Users\Thérèse\AppDat
  a\Local\Programs\Python\Python37-32\Scripts\pyinstaller-script.py on line 1, but
   no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
  </code></pre>
  
  <p>I went to the python.org but I dont really understand what is the fix, please not that I am a beginner in python</p>
