If there is no results, it is a strong indicator that the source is binary/not text. By default, the process will extract 5 blocs of 512o each to assess the mess and coherence of a given sequence. And will give up a particular code page after 20% of measured mess. Those criteria are customizable at will. The preemptive behavior DOES NOT replace the traditional detection workflow, it prioritize a particular code page but never take it for granted. Can improve the performance. You may want to focus your attention to some code page or/and not others, use cp_isolation and cp_exclusion for that purpose. This function will strip the SIG in the payload/sequence every time except on UTF-16, UTF-32. By default the library does not setup any handler other than the NullHandler, if you choose to set the 'explain' toggle to True it will alter the logger configuration to add a StreamHandler that is suitable for debugging. Custom logging format and handler can be set manually. z4Expected object of type bytes or bytearray, got: {0}r z<Encoding detection on empty bytes, assuming utf_8 intention.�utf_8g F� Nz`cp_isolation is set. use this flag for debugging purpose. limited list of encoding allowed : %s.z, c S s g | ]}t |d ��qS )F)r )�.0�cp� r+ �G/opt/alt/python37/lib/python3.7/site-packages/charset_normalizer/api.py� <listcomp>] s z from_bytes.<locals>.<listcomp>zacp_exclusion is set. use this flag for debugging purpose. limited list of encoding excluded : %s.c S s g | ]}t |d ��qS )F)r )r) r* r+ r+ r, r- h s z^override steps (%i) and chunk_size (%i) as content does not fit (%i byte(s) given) parameters.r z>Trying to detect encoding from a tiny portion of ({}) byte(s).zIUsing lazy str decoding because the payload is quite large, ({}) byte(s).z@Detected declarative mark in sequence.
