test_strptime and test_time fail on non-English Windows.

For example:

======================================================================
FAIL: test_localtime_timezone (test.test_time.TestPytime)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "C:\Users\Serhiy Storchaka\py\cpython\lib\test\test_time.py", line 643, in test_localtime_timezone
    self.assertEqual(lt.tm_zone, time.tzname[lt.tm_isdst])
AssertionError: 'O?ieyia?y (e?oi)' != '\xd4\xb3\xed\xeb\xff\xed\xe4\xb3\xff (\xeb\xb3\xf2\xee)'
- O?ieyia?y (e?oi)
+ \xd4\xb3\xed\xeb\xff\xed\xe4\xb3\xff (\xeb\xb3\xf2\xee)

Seems there are problems with wrong encodings and lossy encoding on Windows.

>>> '\xd4\xb3\xed\xeb\xff\xed\xe4\xb3\xff (\xeb\xb3\xf2\xee)'
'Ô³íëÿíä³ÿ (ë³òî)'

Looks similar to the string 'O?ieyia?y (e?oi)', isn't?

>>> 'ô³íëÿíä³ÿ (çèìà)'.encode('latin1').decode('cp1251')
'фінляндія (зима)'

Actually it is a string 'фінляндія (зима)' ('Finland (Summer)' in Ukrainian) encoded with cp1251 (Cyrillic ANSI encoding) and misinterpreted as encoded with Latin1.
