Package encodings

Standard "encodings" Package

    Standard Python encoding modules are stored in this package

    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 ''.

    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().

Function Details [hide private]



Normalize an encoding name.

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.
