Sorry, I was imprecise.
I wanted to say that the above snippet
does not work both on Windows and Linux.
This is what I get on Windows:
>>> import sys
'3.2 (r32:88445, Feb 20 2011, 21:29:02) [MSC v.1500 32 bit (Intel)]'
>>> locale.setlocale(locale.LC_ALL, (myISOCountryCode, locale.getpreferredencoding()))
Traceback (most recent call last):
File "<pyshell#113>", line 1, in <module>
File "C:\apps\Python32\lib\locale.py", line 538, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting
The snippet actually works on Linux, as you note.

That's because currently I care most about
lists of strings being sorted properly (see below).
Nevertheless, it *appears* to me that, in the Unicode era,
the locales could well be decoupled from particular encodings.
But this is another topic.

It's not that I care about encoding,
it's that Windows throws locale.Error at me :-)

For the moment, I only wish to properly sort a Croatian text file
both on Windows and Linux (I am a cautious guy, I like reachable
When the locale is properly set, sorting works like a charm
My current solution to the portability problem is:
locale.setlocale(locale.LC_ALL, 'hr_HR.utf8') # linux
locale.setlocale(locale.LC_ALL, 'Croatian_Croatia.1250') #
Thanks for your feedback!
