This module defines: 1. **Directional supersets** for accuracy evaluation: detecting a superset encoding when the expected encoding is a subset is correct (e.g., detecting utf-8 when expected is ascii), but not the reverse. 2. **Bidirectional equivalents**: groups of encodings where detecting any member when another member was expected is considered correct. This includes UTF-16/UTF-32 endian variants (which encode the same text with different byte order) and ISO-2022-JP branch variants (which are compatible extensions of the same base encoding). 3. **Preferred superset mapping** for the ``should_rename_legacy`` API option: replaces detected ISO/subset encoding names with their Windows/CP superset equivalents that modern software actually uses. ) annotationsN) DetectionDictc[R"U5R$![a3 UR 5R SS5R SS5s$f=f)zNormalize encoding name for comparison. :param name: The encoding name to normalize. :returns: The canonical codec name, or a lowered/stripped fallback. -_)codecslookupname LookupErrorlowerreplace)r s T/var/www/html/banglarbhumi/venv/lib/python3.13/site-packages/chardet/equivalences.pynormalize_encoding_namersQ >}}T"''' >zz|##C,44S"==>s":AAasciizutf-8z windows-1252tis-620 iso-8859-11cp874gb2312gb18030gbkbig5 big5hkscscp950 shift_jiscp932shift_jis_2004zshift-jisx0213zeuc-jpz euc-jis-2004z euc-jisx0213euc-krcp949cp037cp1140z iso-2022-jp> iso2022-jp-2iso2022-jp-extiso2022-jp-2004z iso2022-jp-1r"r#z iso2022-jp-3r$ iso-8859-1 iso-8859-2z windows-1250z windows-1251z windows-1256z windows-1253z windows-1255z windows-1254z windows-1257) iso-8859-5 iso-8859-6 iso-8859-7 iso-8859-8 iso-8859-9 iso-8859-13dict[str, frozenset[str]] SUPERSETSz Windows-1252CP949z Windows-1250z Windows-1251z Windows-1256z Windows-1253z Windows-1255z Windows-1254CP874z Windows-1257) rrr%r&r'r(r)r*r+rr,rzdict[str, str]PREFERRED_SUPERSETcURS5n[U[5(a'[RUR 5U5US'U$)a#Replace the encoding name with its preferred Windows/CP superset.
