/* ------------------------------------------------------------------------
_codecs -- Provides access to the codec registry and the builtin
codecs.
This module should never be imported directly. The standard library
module "codecs" wraps this builtin module for use within Python.
The codec registry is accessible via:
register(search_function) -> None
lookup(encoding) -> CodecInfo object
The builtin Unicode codecs use the following interface:
<encoding>_encode(Unicode_object[,errors='strict']) ->
(string object, bytes consumed)
<encoding>_decode(char_buffer_obj[,errors='strict']) ->
(Unicode object, bytes consumed)
These <encoding>s are available: utf_8, unicode_escape,
raw_unicode_escape, latin_1, ascii (7-bit), mbcs (on win32).
