This is what I see on my Hungarian Windows:


C:\Users\User>python
Python 2.7.1 (r271:86832, Nov 27 2010, 17:19:03) [MSC v.1500 64 bit 
(AMD64)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> import locale
 >>> locale.setlocale(locale.LC_ALL, '')
'Hungarian_Hungary.1250'
 >>> locale.getlocale()
('Hungarian_Hungary', '1250')
 >>>

So I'm 100% sure that the problem is with your system locale settings, 
not Python.

All right. But you understand, that Croatian ISO8859-2 is not supported 
on windows? So you will not be able to sort names with that under a 
windows system? (And it is not a limitation of Python.)

Well, all right. If you want to sort Croatian names from a program that 
runs on an English (or whatever) system, then you will have to check the 
platform and use a locale that is supported by the platform. (But again, 
this is not Python's limitation. Python doesn't know what encodings are 
supported, in advance, and you cannot use a locale that is not supported...)

Croatian users will most likely use a Croatian Windows, out of the box. 
And on those systems, using locale.setlocale(locale.LC_ALL, '') will 
work perfectly. I'm not sure why it doesn't work on an English Windows 
with locale changed... I'm not a big fan of Windows, but I remember once 
I had to install a language pack for Windows before I could use a 
localized program. This might be what you need?

Best,
