The default encoding method is 'ascii'.  You probably want
to use 'utf-16'.  Therefore...:

>>> s=u'\u0141\u0142'

>>> s
>>> print s
Traceback (innermost last):
  File "<pyshell#2>", line 1, in ?
    print s
UnicodeError: ASCII encoding error: ordinal not in range(128)
>>> print s.encode('utf-16')
>>> s.encode('utf-16')

Note that the first 2 bytes in an utf-16 encoding are the
byte-order marks (little or big endian).  They only go
at the _start_ of a utf-16 encoded Unicode textfile, so
you may need to append a [2:] slicing (to all but the
first string being written) if you write several strings
to a file one after the other (there may be less-kludgy
ways, of course...).
