UnicodeEncodeError with Unicode query parameter

[fnielsen]

I get a UnicodeEncodeError with Unicode query parameter with the present 'pip' version.

>>> db.query(u"select * from words where form == '{{ word }}' limit 10", data={'word': u'læge'})
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/db/db.py", line 1307, in query
    q = self._apply_handlebars(q, data, union)
  File "/usr/local/lib/python2.7/dist-packages/db/db.py", line 1144, in _apply_handlebars
    query = str(query)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe6' in position 36: ordinal not in     range(128)

In the present GitHub version the error occurs in line 1232.

I have no problem if I interpolate before calling the query method, i.e., avoid self._apply_handlebars.

>>> db.query(u"select * from words where form == 'læge' limit 10")
   index        id  form   pos
