Request params encoded using system encoding

Perhaps I’m misunderstanding how this is supposed to work, but it looks like all request parameters are encoded using the system locale encoding. (https://github.com/wagnerrp/pytmdb3/blob/master/tmdb3/request.py#L70) This causes problems when the system locale cannot encode all the charaters in the parameters, plus, I have no idea how tmdb is expected to know what encoding you have used to encode the parameters, I suspect it should be using a constant encoding defined by the tmdb api. Portion of a relevant traceback:

File "/usr/local/lib/python2.7/dist-packages/flexget/plugins/api_tmdb.py", line 293, in lookup
    result = _first_result(tmdb3.tmdb_api.searchMovie(title.lower(), adult=True, year=year))
  File "/usr/local/lib/python2.7/dist-packages/tmdb3/tmdb_api.py", line 128, in searchMovie
    return MovieSearchResult(Request('search/movie', **kwargs), locale=locale)
  File "/usr/local/lib/python2.7/dist-packages/tmdb3/request.py", line 71, in __init__
    kwargs[k] = locale.encode(v)
  File "/usr/local/lib/python2.7/dist-packages/tmdb3/locales.py", line 110, in encode
    return dat.encode(self.encoding)
UnicodeEncodeError: 'latin-1' codec can't encode characters in position 0-13: ordinal not in range(256)

Did a bit of testing, looks like tmdb is expecting utf-8 encoding. Did a bit of a hack to get things working again:

# Before. Broken
>>> tmdb3.tmdb_api.searchMovie(u'Generation П')[0]
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "build\bdist.win32\egg\tmdb3\tmdb_api.py", line 128, in searchMovie
    return MovieSearchResult(Request('search/movie', **kwargs), locale=locale)
  File "build\bdist.win32\egg\tmdb3\request.py", line 70, in __init__
    kwargs[k] = locale.encode(v)
  File "build\bdist.win32\egg\tmdb3\locales.py", line 110, in encode
    return dat.encode(self.encoding)
  File "C:\Users\chase.sterling\PycharmProjects\Flexget\lib\encodings\cp1252.py", line 12, in encode
    return codecs.charmap_encode(input,errors,encoding_table)
UnicodeEncodeError: 'charmap' codec can't encode character u'\u041f' in position 11: character maps to <undefined>

# Hack to fix encoding
>>> tmdb3.locales.set_locale("en", "us", True)
>>> tmdb3.locales.syslocale.encoding = 'utf-8'

# After. Working.
>>> tmdb3.tmdb_api.searchMovie(u'Generation П')[0]
<Movie 'Generation P' (2011)>

tmdb3.locales.syslocale.encoding = 'utf-8' fixed also TMDbError Internal error - Something went wrong. Contact TMDb. on tmdb3.MovieSearch('some string with äüö') Thanks @gazpachoking !
