用xlutils.copy 将中文写入excel文档中

遇到的问题1：

Traceback:

TypeError: coercing to Unicode: need string or buffer, NoneType found

用xlutils写文件的时候报这个错了。

需要把下面这部分改成下面这样才好使。

start from line45)
def upack2(s, encoding='ascii'):
# If not unicode, make it so.
if isinstance(s, unicode):

elif s is not None:
us = unicode(s, encoding)
else:
us = unicode('', encoding)

遇到的问题2：

写入中文，需要将

Workbook.py中的初始化改为utf8,原来默认的是ascii

def __init__(self, encoding='utf8', style_compression=0):
