the error following:

2015-06-13 19:42:21,743 __main__ -    error - [  1]   1 exception: 'ascii' codec can't encode character u'\xb4' in position 40: ordinal not in range(128) <type 'exceptions.unicodeencodeerror'> 2015-06-13 19:42:30,962 __main__ -    error - [  1]   1 exception: 'ascii' codec can't encode character u'\xb4' in position 27: ordinal not in range(128) <type 'exceptions.unicodeencodeerror'>

i noticed given data gets uploaded, not sure if rows uploaded.

thanks!

try before putting csv db s.decode('utf-8') , after getting out of db s.encode('utf-8')

i did sqlite , worked ok.
