CentOS 7 / Apache / mod_wsgi - UnicodeDecodeError：‘ascii’編解碼器無法解碼位置 2727 的字節 0xc2：序數不在範圍內（128）

我已經使用 mod_wsgi 在 Apache (httpd) 中部署了一個 Python Web 應用程序（使用 Pyramid）。

啟動 Apache 服務後，當我們向 Web 應用程序發出 http 請求時，會出現以下錯誤（來自 Apache 日誌）…

該 web python 應用程序在所有這些發行版中都能完美執行：Ubuntu 14.04、Debian 8、RedHat 6、CentOS 6、Suse 12 和 openSUSE 13，但在 CentOS 7 中則不行… =[

我們在“CentOS 7”中使用“Python 3.2.2”、“mod_wsgi 4.3.2”和“Apache 2.4.6”。Web 應用程序建構在Pyramid Web 框架 ( http://docs.pylonsproject.org/projects/pyramid/en/latest/ ) 之上。

這是一個相當常見的錯誤！到目前為止，我還沒有找到一種方法來獲取有關此錯誤的更多資訊。

我們已經嘗試了一切來解決這個問題，但我們根本不知道它為什麼會發生…… =[

請幫我！

出現此問題是因為/etc/mime.typesCentOS 7 的文件中包含對 ascii 無效（未擴展）的字元"³"（行"application/vnd.geocube+xml g3 g³"）。

為了弄清楚這一點，我必須對我的 Python 3.2.2 進行一些修改並重新載入我的應用程序。

解決方案是刪除"³"字元或任何其他無效（ascii）字元！
