If you have a byte string (the standard in Python 2) you have to decode(), 
i. e. convert it to unicode) before you format it. Compare:

>>> names = "Angie Dickons", "Anne Méresse"
>>> for name in names:
...     print "|{:20}|".format(name)
... 
|Angie Dickons       |
|Anne Méresse       |
>>> for name in names:
...     name = name.decode("utf-8")
...     print u"|{:20}|".format(name)
... 
|Angie Dickons       |
|Anne Méresse        |

The best approach is to convert your data to unicode as soon as you read it 
and perform all string operations with unicode. This also avoids breaking 
characters:

>>> print "Méresse"[:2]
M�                                                                                                                                                    
>>> print u"Méresse"[:2]
Mé

There are still problems (e. g. with narrow builds), and the best way to 
avoid a few string-related inconviences is to switch to Python 3.
