Hello,

I'm having trouble with the babel evaluation of python blocks containing
utf-8 encoded characters (which is the encoding of my org file).

I tried the approach suggested in this message
https://lists.gnu.org/archive/html/emacs-orgmode/2010-12/msg00086.html
in the following block

#+BEGIN_SRC python :prefix # -*- coding: utf-8 -*- :results output
print(u'∀')
#+END_SRC

but when I evaluate it, I get an error

  File "<stdin>", line 1
SyntaxError: Non-ASCII character '\xe2' in file <stdin> on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

Am I doing something wrong?

Thanks,

Alan

I see that somewhere the email did not get through, the character above
is a "forall" character. I have the same problem with a simpler accent

#+BEGIN_SRC python :prefix # -*- coding: utf-8 -*- :results output
print(u'é')
#+END_SRC

I also see the same problem here. Even if you include   # -*- coding: utf-8 -*-    as the first line.

Shouldn't org-babel already be using utf-8 instead of ASCII for input/output?


By the way, with Python3 it doesn't happen since it doesn't need the coding:utf-8 declaration anymore.

Should this be considered a bug, or do we require python 3 for such
things?

Thanks,

Alan

I think if the user writes the # -*- coding: utf-8 -*- line, org-mode should pass it. With that, all Pythons (Python2, Python3) work well, so I wouldn't say there's a bug in Python. It would be in org-mode.
