This is usually problem with C API providing C-style strings 
(bytes in Pythonesque) and Python expects Python strings (str in 
Pythonesque). Also, what encoding C library uses? Is it really 
UTF-8? If not (and it is for example Windows-friendly UTF-16) 
str.decode('utf-16') conversion must be done to get proper 
Python str object.

Best,
