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 return 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. uasciiu.u_uFT(u isinstanceubytesustruFalseuisalnumuappenduTrueujoin(uencodingucharsupunctuc((u7/opt/alt/python33/lib64/python3.3/encodings/__init__.pyunormalize_encoding*s unormalize_encodingc "Cs/tj|t�}|tk r"|St|�}tj|�pUtj|jdd��}|dk rs||g}n |g}xc|D]U}|s�d|kr�q�ny td|dtdd�}Wnt k r�Yq�XPq�Wd}y |j }Wntk r d}YnX|dkr$dt|s S
