Jython doesn't handle Unicode strings properly when using sun.locale.formatasdefault=true flag. 

Preconditions:
- Window 7, OS language English and regional settings (including date formats) set to Finnish

Steps to reproduce:
- start Jython by "java -Dsun.locale.formatasdefault=true -jar jython-standalone-2.7.0.jar"
- enter to console:
-- from datetime import datetime
-- datetime.strptime('pe tammi 22 14:00:00 2016', u'%a %b %d %H:%M:%S %Y')

Result:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Z:\Lauri\jython-standalone-2.7.0.jar\Lib\datetime.py", line 1778, in strptime
  File "Z:\Lauri\jython-standalone-2.7.0.jar\Lib\_strptime.py", line 308, in _strptime

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe3 in position 18: ordinal not in range(128)

After removing the "u" from format-string this issue doesn't reproduce.

Originally happens when using RobotFramwork's DateTime-library and apparently there strings are using Unicode so using this without the "u" is not an option for me.
