[docs] Doctest problem

[minz]

Hello!
I have a following problem (maybe it is a bug) while running this:
# coding: utf-8

class test(object):
    """
    ОЛОЛО ПЫЩПЫЩ
    >>> print 1 # ошибка
    1
    >>> obj = test()
    >>> obj.raiser() # ошибка
    Traceback (most recent call last):
        ...
    Exception
    """
    def __init__(self):
        pass
        
    def raiser(self):
        raise Exception

if __name__ == "__main__":
    import doctest
    doctest.testmod()


$ python pybug.py
Traceback (most recent call last):
  File "pybug.py", line 22, in <module>
    doctest.testmod()
  File "/usr/lib/python2.6/doctest.py", line 1848, in testmod
    runner.run(test)
  File "/usr/lib/python2.6/doctest.py", line 1391, in run
    return self.__run(test, compileflags, out)
  File "/usr/lib/python2.6/doctest.py", line 1277, in __run
    got += _exception_traceback(exc_info)
  File "/usr/lib/python2.6/doctest.py", line 244, in
_exception_traceback
    traceback.print_exception(exc_type, exc_val, exc_tb, file=excout)
  File "/usr/lib/python2.6/traceback.py", line 125, in print_exception
    print_tb(tb, limit, file)
  File "/usr/lib/python2.6/traceback.py", line 69, in print_tb
    line = linecache.getline(filename, lineno, f.f_globals)
  File "/usr/lib/python2.6/linecache.py", line 14, in getline
    lines = getlines(filename, module_globals)
  File "/usr/lib/python2.6/doctest.py", line 1336, in
__patched_linecache_getlines
    source = example.source.encode('ascii', 'backslashreplace')
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 15:
ordinal not in range(128)

The problem is in the comment in line ">>> obj.raiser() # ошибка".
Removing this comment or even moving it to previous line removes the
error. 
First test (>>> print 1 # ошибка) without the second one works fine.
I have 2.6.6-5ubuntu1 installed:
$ python -V
Python 2.6.6
