If there is no results, it is a strong indicator that the source is binary/not text. By default, the process will extract 5 blocks 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. z3Expected object of type bytes or bytearray, got: {}rzlzfrom_bytes..zacp_exclusion is set. use this flag for debugging purpose. limited list of encoding excluded : %s.cSr8r9r:r;rrrr>wr?z^override steps (%i) and chunk_size (%i) as content does not fit (%i byte(s) given) parameters.rz>Trying to detect encoding from a tiny portion of (%i) byte(s).zIUsing lazy str decoding because the payload is quite large, (%i) byte(s).z@Detected declarative mark in sequence.
