中文时间日期解析错误-UnicodeEncodeError: ‘locale’ codec can’t encode character ‘\u5e74’ in position 2: Illegal

参考：https://segmentfault.com/q/1010000003070325

       word = (datetime.today() + timedelta(days=keyDate.get(k, 0))).strftime('%Y年%m月%d日')

报错：“UnicodeEncodeError: 'locale' codec can't encode character '\u5e74' in position 2: Illegal byte sequence“”

更改为：
   word = (datetime.today() + timedelta(days=keyDate.get(k, 0))).strftime('%Y{y}%m{m}%d{d}').format(y='年', m='月', d='日')
