I don't know what to paste, so i paste this:

$ python
Python 2.6.6 (r266:84292, Nov 21 2013, 12:39:37) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2

>>> data = {'from': '\u017b'}
>>> print(type(data['from'])) 
<type 'str'>
>>> string = '  <td>{from}</td>\n'.format(**data)
>>> print string
  <td>\u017b</td>

and then:

>>> data = {'from': u'\u017b'}
>>> print(type(data['from'])) 
<type 'unicode'>
>>> string = '  <td>{from}</td>\n'.format(**data)
Traceback (most recent call last):

UnicodeEncodeError: 'ascii' codec can't encode character u'\u017b' in

... and ...

>>> import os
>>> print os.environ['LANG']
en_US.UTF-8
