UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-3: ordinal not in range(128)

py文件直接在cmd窗口用python命令执行时正常；代码逐句在ipython中也正常；但是，

在wingIDE中运行报错“UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-3: ordinal not in range(128)”

解决方案是在python的Lib文件夹下新建一个sitecustomize.py，内容为：

# coding=utf-8
import sys

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