Strange output

[mjdunn]

I tried using your lib with both 2.7.11 and 3.5.1. Py3 definitely seems to work better, but I'm getting odd output for some chars in both. For example:

$ python3                   
>>> from xpinyin import Pinyin
>>> p = Pinyin()
>>> p.get_pinyin(u"秋")
'qiu'
>>> p.get_pinyin(u"秋", show_tone_marks=True)
'qiū!!!!'

$ python
>>> from xpinyin import Pinyin
>>> p = Pinyin()
>>> p.get_pinyin(u"秋")
u'qiu'
>>> p.get_pinyin(u"秋", show_tone_marks=True)
u'qi\u016b!!!!'
