add support for encoding unicode strings

[jdelic]

Currently the following "doesn't work":

>>> f = furl('http://example.com')
>>> f.args[u'testö'] = u'testä'
>>> f
<repr(<furl.furl.furl at 0x17438d0>) failed: UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 4: ordinal not in range(128)>

The documentation explicitly states "Encoding is handled for you" and, of course, means urlencoding, however urllib.urlencode does not automatically handle unicode.

>>> f.args[u'testö'.encode('utf-8')] = u'testä'.encode('utf-8')

"works".

Great find.

I'll fix this shortly.

furl v0.3.8 supports unicode query keys and values.

>>> f = furl('http://site4dads.ru/')
>>> f.args[u'testö'] = u'testä'
>>> f.url
'http://site4dads.ru/?test%C3%B6=test%C3%A4'

Update to v0.3.8 with

pip install furl --upgrade

Thank you for bringing this issue to my attention @jdelic.
