Expected behavior of string.Formatter() is to return unicode strings for unicode templates, and "byte" strings for str templates. Which is exactly what it does, with one frustrating exception: for empty unicode string it returns byte str. Test follows: import string template = u"" result = string.Formatter().format(template) assert isinstance(result, unicode) # AssertionError
