python 3: test_to_string_truncate_indices  UnicodeEncodeError: 'ascii' codec can't encode characters in position 177-178: ordinal not in range(128)
Was trying to build a fresh pkg of current master 0.14.0~rc1+git73-g8793356 and got hiccup with

```
======================================================================
ERROR: test_to_string_truncate_indices (pandas.tests.test_format.TestDataFrameFormatting)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/tmp/buildd/pandas-0.14.0~rc1+git73-g8793356/debian/tmp/usr/lib/python3/dist-packages/pandas/tests/test_format.py", line 414, in test_to_string_truncate_indices
    print(df)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 177-178: ordinal not in range(128)

Ran 6694 tests in 557.813s

FAILED (SKIP=482, errors=1)
```

please do not "print" in the tests... makes it harder to get through the output to the actual report on failures (and `assert("blah" in str(df))` and `assert("bleh" in repr(df))` would be more functional)
