There are no locales available except C, at least to lua and python:

% which lua
/home/cfl/.nix-profile/bin/lua
% lua
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio
> print(os.setlocale('en_US.utf-8'))
nil
> print(os.setlocale('en_US.UTF-8'))
nil
> print(os.setlocale('en_US.ISO-8859-1'))
nil
> print(os.setlocale('C'))    
C

The nil means, it failed to set the locale.


% which python
/home/cfl/.nix-profile/bin/python
% python
Python 2.7 (r27:82500, Aug 17 2010, 05:43:32) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale
>>> locale.getdefaultlocale()
('en_US', 'UTF8')
>>> locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/nix/store/f9y4kmb9lflqkgjwavlf8mjj06r3pxhq-python-2.7/lib/python2.7/locale.py", line 531, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting
>>> locale.setlocale(locale.LC_ALL, 'C')                  
'C'

The getdefaultlocale() shows what is set in the environment, but to really use
it, one needs to set it manually in python.


I found documentation for nixos[1], but not for nix on some other
system. In ubuntu (the host system) the locales are correctly configured
and functional.
