superset accii

superset demo 搭建完成，能够访问页面啦， 但是对数据进行访问时， 总是报错， 提示信息：

Traceback (most recent call last):

    '(id:{obj.id})').format(obj=self)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

解决问题的方法是在 ${PY_HOME}/site-packages/下创建一个  sitecustomize.py 文件， 同时添加源码：

import sys 


reload(sys)
sys.setdefaultencoding('UTF-8') 

然后重新启动superset，然后访问正常
