最近在用linux做android开发，之前在弄输入法，把ibus替换为fcitx,之中大概是删掉了系统中的一些语言包。

当时也没在意。

后来开始用repo工具更新源码，开始报错：

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 25: ordinal not in range(128)
niyaou@niyaou:~/

查了一下，大概是ASCII转码UTF-8的时候出错。

解决办法

找到python所在目录   

/usr/lib/python2.7/site-packages/sitecustomize.py

加入以下代码

import sys
sys.setdefaultencoding("utf-8")

搞定
