This is what I've put into /python2.3/locale.py:

locale_alias = {....
    .......
    'bokmål':			'nb_NO.ISO8859-1',
    'nb':			  'nb_NO.ISO8859-1',
    'nb_no':			'nb_NO.ISO8859-1',
    'nynorsk':			'nn_NO.ISO8859-1',
    'nn':			  'nn_NO.ISO8859-1',
    'nn_no':		        'nn_NO.ISO8859-1',
   ....
   ....
}

I have tested it on a number of apps and it fixes the problem.

Please provide some authorative source which describes the
locale your are using (nb_NO) and the commonly used encoding
for that locale (see the existing dictionary in locale.py).

The reason I use getdefaultlocale(), is to get a platform
independant way of getting the systems locale setting.
The biggest advantage is that on Windows a "Linux like"
locale is returnt so that I can use the same language
support stuff on all
platforms. (Win,Linux,OSX).
Besides, what's the problem of adding the missing locale?

The LANG (and other similar OS environment variables) define
what the user wishes to see being used as locale in the
applications that are started in that environment. See the
setlocale man page for details.

On some OSes such as Windows these settings are stored
differently, which is why the locale module has provisions
for finding these settings (thanks to Fredrik).

There is no "default locale setting" in most operating
systems. In what sense is the value of the LANG environment
variable a "default"?

Of course, I don't agree with you, Martin :-)
locale.getdefaultlocale() does server a purpose, namely that
of getting the default locale setting. The encoding
information is an often used extension when setting the
locale in the OS environment. If not set, the module
provides common defaults.

The locale "nb_NO" is not known to the module alias table.
Which locale, language and encoding would that be ?

To get the default encoding for the current locale, you
should use locale.getpreferredencoding(). You should not use
getdefaultlocale becaus it is (IMO) inherently broken, and
should not have been part of the standard library in the
first place.

getdefaultlocale() is often used to get default encoding for
current system locale.
And, if function is provided in standard library, why
shouldn't one use it?

Why do you want to use getdefaultlocale()?
