To get a ``dict`` containing an encoding and its confidence, you can simply run: .. code:: u = UniversalDetector() u.feed(some_bytes) u.close() detected = u.result g�������?s [�-�]s (|~{)s [�-�]s Windows-1252s iso-8859-1s Windows-1250s iso-8859-2s Windows-1251s iso-8859-5s Windows-1256s iso-8859-6s Windows-1253s iso-8859-7s Windows-1255s iso-8859-8s Windows-1254s iso-8859-9s Windows-1257s iso-8859-13c C sq d | _ g | _ d | _ d | _ d | _ d | _ d | _ | | _ t j t � | _ d | _ | j � d S( N( t Nonet _esc_charset_probert _charset_proberst resultt donet _got_datat _input_statet _last_chart lang_filtert loggingt getLoggert __name__t loggert _has_win_bytest reset( t selfR ( ( sI /usr/lib/python2.7/site-packages/pip/_vendor/chardet/universaldetector.pyt __init__Q s c C s� i d d 6d d 6d d 6| _ t | _ t | _ t | _ t j | _ d | _ | j rg | j j � n x | j D] } | j � qq Wd S( s� Reset the UniversalDetector and all of its probers back to their initial states.

After calling ``feed``, you can check the value of the ``done`` attribute to see if you need to continue feeding the ``UniversalDetector`` more data, or if it has made a prediction (in the ``result`` attribute). .. note:: You should always call ``close`` when you're done feeding in your document if ``done`` is not already ``True``.
