我已经使用mod_wsgi在Apache（httpd）中部署了Python Web应用程序（使用金字塔）。
启动Apache服务后，当我们向Web应用程序发出http请求时，会发生下面的错误（来自Apache日志）…

我们在“CentOS 7”中使用“Python 3.2.2”，“mod_wsgi 4.3.2”和“Apache 2.4.6”。 该Web应用程序build立在Pyramid Web框架之上（ http://docs.pylonsproject.org/projects/pyramid/en/latest/ ）。
这是一个相当常见的错误！ 到目前为止，我还没有find一个方法来获取有关此错误的更多信息。
我们已经尽了一切努力来解决这个问题，我们根本不知道为什么会发生… = [
请帮帮我！
发生这个问题是因为CentOS 7的/etc/mime.types文件的字符为"³" （行"application/vnd.geocube+xml g3 g³" ），这对ascii（不扩展）是无效的。
为了解决这个问题，我不得不对Python 3.2.2做一些修改，重新加载我的应用程序。
解决办法是删除"³"字符或任何其他无效（ascii）字符！

谢谢！
