Probably one of

_(...)

or

smart_str(...)

returns unicode and the other returns a non-ascii bytestring:

>>> u"%s" % "\xe2"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 0: 
ordinal not in range(128)
>>> "\xe2 %s" % u"foo"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 0: 
ordinal not in range(128)

Probably not. If you entered non-ascii text into a form, and can limit 
yourself to ascii-only then that might be a workaround...
