The problem is, python 2.x assumed the default encoding of `ascii`
whenever you don't explicitly mention the encoding, and your code
apparently broke with that assumption. I haven't looked at your code,
but others have suggested that you've fed the logging module with
non-ascii byte strings. The logging module can only work with 1) unicode
string, 2) ascii-encoded byte string
If you want a quick fix, you may be able to get away with repr()-ing
your log texts. A proper fix, however, is to pass a unicode string to
the logging module instead.
>>> logging.warn('ы') # or logging.warn('\xd1\x8b')
Traceback (most recent call last):
