Except the two objects are not different if default encoding is utf-8.

(Whether it's a good idea to change the default encoding is another
question, but Python is clearly documented as behaving this way.  When
comparing a byte string and a Unicode string, the byte string will be
decoded according to the default encoding.)

I believe the OP's point was to show that dicts behave differently
than lists here ("in" works for lists, doesn't work for dicts).
