我试了：

还按这上面试了：http://www.07net01.com/linux/Djangochuxiande_ascii__codec_can_t_encode_characters_in_positio_11063_1345791548.html

上面说是在

在/etc/apache2/envvars文件加上：

export LANG='en_US.UTF-8'export LC_ALL='en_US.UTF-8'

我是用的centos 没找到envvars 不知道在哪里加？

我直接在/etc/httpd 里建了一个envvars 然后加上上面的代码。然后重启服务器还是不管用。

我是用的django1.52+python2.6 　+mod_wsgi apache centos  这个还有别的什么办法处理不？
