+Hello,\r
+\r
+I have come across a problem with Unicode [1] in afew mail filter which\r
+uses Notmuch Python bindings and it has eventually bringed us to\r
+confusion about Unicode handling in Python bindings.\r
+\r
+Shouldn't __unicode__() methods return value of type unicode? Let's\r
+take an example of __unicode__() method from Message class:\r
+\r
+ def __unicode__(self):\r
+ format =3D "%s (%s) (%s)"\r
+ return format % (self.get_header('from'),\r
+ self.get_tags(),=20=20=20=20=20=20=20=20=20=20=20=\r
+=20=20=20=20=20\r
+ date.fromtimestamp(self.get_date()),\r
+ )\r
+\r
+format is of type str, not unicode and method is eventually going to\r
+return str, while the user of the API is expecting unicode type.\r
+\r
+I haven't programmed in Python 3, yet - only in Python 2, so maybe I am\r
+missing something. When I was writing a big project in Python 2, I have\r
+eventually decided to use u'' literals everywhere and decode any str to\r
+unicode ASAP - and this solved all issues wrt encodings. I guess that\r
+mixing Python 2 and 3 gets even more problematic.\r
+\r
+Could you review (and fix if it is needed) Python bindings in context of\r
+unicode handling, please?\r
