Codecs must currently use names as defined by the search function in the
encodings package:
Codec modules must have names corresponding to standard lower-case
encoding names with hyphens mapped to underscores, e.g. 'utf-8' is
implemented by the module 'utf_8.py'.
We could extend this to:
Codec modules must have names corresponding to standard lower-case
encoding names with all non-alphanumeric charactersmapped to
underscores, e.g. 'utf-8' is implemented by the module 'utf_8.py'
and 'ISO 639:1988' would be implemented as module 'iso_639_1988'.
Note that the aliasing dictionary is consulted *after*
having applied this mapping.
