Codec modules must have names corresponding to normalized encoding names as defined in the normalize_encoding() function below, e.g. 'utf-8' must be implemented by the module 'utf_8.py'. Each codec module must export the following interface: * getregentry() -> codecs.CodecInfo object The getregentry() API must a CodecInfo object with encoder, decoder, incrementalencoder, incrementaldecoder, streamwriter and streamreader atttributes which adhere to the Python Codec Interface Standard. In addition, a module may optionally also define the following APIs which are then used by the package's codec search function: * getaliases() -> sequence of encoding name strings to use as aliases Alias names returned by getaliases() must be normalized encoding names as defined by normalize_encoding().

Normalization works as follows: all non-alphanumeric characters except the dot used for Python package names are collapsed and replaced with a single underscore, e.g. ' -;#' becomes '_'. Leading and trailing underscores are removed. Note that encoding names should be ASCII only; if they do use non-ASCII characters, these must be Latin-1 compatible. tunicodeslatin-1t_( thasattrt __builtin__t isinstanceRtencodetjoint translatet_norm_encoding_maptsplit(tencoding((s(/usr/lib/python2.7/encodings/__init__.pytnormalize_encoding1sc Cs8tj|tƒ}|tk r"|St|ƒ}tj|ƒpUtj|jddƒƒ}|dk rs||g}n |g}xb|D]T}| sƒd|kr¢qƒny td|dtddƒ}Wnt k rÕqƒXPqƒWd}y |j }Wnt k rd}nX|dkr"dt|s      V
