That is not the full text of the error message. The full text
includes a stack trace and should always be included verbatim. Copy
and paste rather than retyping as accuracy of the message is
important in helping you.

If good_answer is always manually defined (rather than being retrieved
from somewhere, you can just manually set it to Unicode by prefixing
the string with a 'u'.
good_answer = u'pureté' # acute accent and now Unicode!
Otherwise you will have to use one of the below lines.
good_answer.decode(<encoding format>) # converts to Unicode.
# answer_given.encode(<encoding format>) # converts from Unicode to format

Unicode is fairly complex, but maybe this[0] will help if you run into
problems (or just come back to the list). You can find the list of
encoding formats (called codecs) here[1].

This list prefers the usage of plain text emails as HTML can
remove indentation and since Python's indentation is
significant it makes it much more difficult to help you.
Also, top posting discouraged in favor of either bottom or
in-line posting. Thanks!
