Yes, you're right Andreas. It "fails" to show the accented characters if you 
try to print the entire tuple.
It fails too if you evaluate a[0][0] in your interpreter. You should see :
>>> a[0][0]
'\xc3\xa9'
But print a[0][0] gives the expected answer 'é'

So, based on your successful experience consisting in returning a[0][0] in 
the orgmode source block, we can assume that org-babel use the python print 
function to display results in org buffer, aren't we? 

Another strange behaviour, when you evaluate the src_block test given in 
example, you get :
| \303\251 | a        |
| a        | \303\240 |

Whereas I was expecting to get the same code than in the python interpreter, 
that is :
| \xc3\xa9 | a          |
| a        | '\xc3\xa0' |

In addition, when I try to save my buffer, Emacs doesn't recognize the 
encoding of characters \303\251 and \303\240 and asks me to choose an 
encoding. Then, I enter utf-8 and nothing happens BUT when I quit and reopen 
my file : the characters are printed correctly.... Too strange for me....

Cheers,

Roland.
