Here is the funniest one:
>>> class C1:
>>> def __repr__(self): return 'foo\nbar'
>>> class C2:
>>> def __repr__(self): return u'foo\nbar'
>>> print repr(C1())
>>> print repr(C2()) # surprise!
The first time I stepped on it, as you might guess, it took me several hours to
figure out what on earth was happening...
And I'm also in a context where, like Alex said, the default behaviour is in my
way: my Tkinter interface is above an application that ends up writing its data
in XML files, encoded in UTF-8 whatever the current default encoding is. So I
control the whole process from top to bottom: UTF-8 in the XML data files, UTF-8
in internal structures and UTF-8 displayed by Tkinter/Tk. So I obviously don't
care about the default encoding anywhere, but I guess it's just the way *I* do
