Summary: IDLE and encodings

Initial Comment:
A person from Belgium reported this problem in IDLE to 

python-help:

$ python  idle

Traceback (most recent call last):

  File "idle", line 10, in ?

    import PyShell

  File "PyShell.py", line 25, in ?

    from EditorWindow import EditorWindow, fixwordbreaks

  File "EditorWindow.py", line 39, in ?

    class EditorWindow:

  File "EditorWindow.py", line 43, in EditorWindow

    from IOBinding import IOBinding

  File "IOBinding.py", line 54, in ?

    codecs.lookup(encoding)

  File

"/ap/tools/storage/python/v2.2.2.224_ap/lib/python2.2/

encodings/__init__.py",

line 51, in search_function

    mod = __import__(modname,globals(),locals(),'*')

ValueError: Empty module name

It seems that checking for an encoding of "" as well as None 

in IOBinding.py fixes the problem. I'll attach his small patch.

Can you report what operating system this was on, and what

locale setting was in place?

What is the value of locale.getpreferredencoding on that system?
