Yep:

>>> s = "\u3141" # HANGUL LETTER MIEUM
>>> f = open('test.txt', 'w')
>>> f.write("\u3141")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character '\u3141' in
position 0: ordinal not in range(128)

Just because the open() call hides the specification of how Python
should do that encoding doesn't prevent the required encoding from
happening. :-)
