Guess the encoding to use

If the output is not a terminal, there's no way python can guess the
encoding to use, so we use system's default encoding

Lucas,

As I've stated in the guiraldelli/Big-e-Mails-Hunter#2 , the locale.getpreferredencoding() unfortunately won't work because it returns a empty string as result. Maybe we should test the sys.stdout.encoding, them locale.getpreferredencoding(); if both of them failure, set ascii as a default encoding.

yes, this should work.
