list doesn't have a __unicode__ method. unicode() therefore converts the
list to str as a fallback and then uses sys.getdefaultencoding() to convert
the result to unicode.

No, it calls repr() on its elements. This is done to avoid confusing output:
>>> items = ["a, b", "[c]"]
['a, b', '[c]']
>>> "[%s]" % ", ".join(map(str, items))
'[a, b, [c]]'
