如何在OSX Mountain Lion中为应用程序包设置默认语言环境

如何设置OS X Mountain Lion中运行应用程序的默认语言环境（LANG，LC_ALL = en_US.UTF-8）？

我正在尝试使用py2app运行打包到.app的Python程序 . 通过双击代码段来运行应用程序时

import locale
print locale.getlocale()

返回（无，无）

但是，通过执行从终端运行应用程序时

opensesame.app/Contents/MacOS/opensesame

getlocale（）函数正确返回（en_US，UTF-8）
（由于终端具有正确的环境设置）

我发现，当双击时，应用程序在不同的环境中运行，而不是从终端运行时，所以现在我正在尝试为应用程序设置默认的编码变量 .

我已经尝试了我发现的建议：How can you get the system default language/locale, in a py2app packaged Python app on Mac OS X?并按照以下说明操作：http://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPInternational/Articles/ChoosingLocalizations.html

我已将CFBundleLocalizations和LSEnvironment键添加到应用程序包内的Info.plist（下面发布），但getlocale（）函数保持returing（None，None）

任何人都可以告诉我为OS X应用程序正确设置这些变量，以便Python选择这些吗？
