_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).
