[lupus]

When i use |date:"d.m.Y в H:i", where "в" is russian letter, i get the following:

Original Traceback (most recent call last):
  File "/home/.../django/template/debug.py", line 72, in render_node
    result = node.render(context)
  File "/home/.../django/template/debug.py", line 88, in render
    output = self.filter_expression.resolve(context)
  File "/home/.../django/template/__init__.py", line 580, in resolve

    return date_format(value, arg)
  File "/home/.../django/utils/formats.py", line 54, in date_format
    return dateformat.format(value, get_format(format or 'DATE_FORMAT'))
  File "/home/.../django/utils/formats.py", line 47, in get_format
    return getattr(settings, format_type)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u0432' in position 6: ordinal not in range(128)
