openstack project list 报错

使用openstack project list时，报以下错误：

'ascii' codec can't encode characters in position 453-457: ordinal not in range(128)

然后通过openstack --debug project list，尝试找到更多的报错信息

由此可见，是client端编码出了问题

检查系统环境变量

echo $LC_ALL， 输出C

确实是编码问题

解决方法是，在admin-openrc.sh脚本中增加：

export LC_ALL='en_US.UTF-8'解决
