[Tutor] unicode help

[Alexandre Conrad]

Marilyn,

You miss-typed the line, it should have a semicolon right after the
word "coding", such as:

# coding: utf-8

not

# coding utf-8

as you showed from your file.

The syntax suggested syntax # -*- coding: utf8 -*- by Martin is
equivalent, but I always have a hard time remembering it from the top
of my head when I create a new Python file. So I just use: # coding:
utf-8
