Walter Dörwald a47d1c08d0 SF bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain 
about illegal code points. The codec now supports PEP 293 style error handlers.
(This is a variant of the Nik Haldimann's patch that detects truncated data)

/* ------------------------------------------------------------------------
_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) -> (encoder, decoder, stream_reader, stream_writer)
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)
<encoding>_encode() interfaces also accept non-Unicode object as
input. The objects are then converted to Unicode using
PyUnicode_FromObject() prior to applying the conversion.
These <encoding>s are available: utf_8, unicode_escape,
raw_unicode_escape, unicode_internal, latin_1, ascii (7-bit),
mbcs (on win32).
