Utf-8 doesn't work on my computer. I tried the exact same code at another computer and it worked but on my computer it doesn't. It's in python.

My program starts like this:

```
# -*- coding: utf-8 -*-    # Behövs i python 2 för åäö

from Tkinter import * 

class Kryssruta(Button):
    """ Knapp som kryssas i/ur när man trycker på den """

    def __init__(self, master, nr = 0, rad = 0, kolumn = 0):
     #Konstruktor, notera master
        Button.__init__(self,master) 
        self.master = master         
        self.rad = rad
        self.kolumn = kolumn
        self.markerad = False
        self.kryssad = False
        self.cirklad = False

        self["command"] = self.kryssa

    def kryssa(self):
        if self.markerad==False: 
            self.master.klickat(self) 

```

On one computer it works like a charm, but on my own computer I get the message.

```
SyntaxError: Non-ASCII character '\xc3' in file 'blah' but no encoding declared;
see http://www.python.org/peps/pep-0263.html for details

```

Using a PC, running in powershell.
Anyone who knows what seems to be the problem?
