关于python：UnicodeDecodeError：’ascii’编解码器无法解码位置0中的字节0xe0：序号不在范围内（128）

UnicodeDecodeError : 'ascii' codec can't decode byte 0xe0 in position 0: ordinal not in range(128)

在我的一台机器上，当我使用google-apps引擎或django时出错。

例如：

App.YAML

当我使用Django中的静态文件(不使用GAE)时，我有非常相似的错误(使用不同的堆栈)。

我试图找出错误的原因，并在mimetypes.py中添加了代码：

print '====='
print ctype
ctype = ctype.encode(default_encoding) # omit in 3.x!

然后我在控制台中收到下一条消息：

在注册表中，hkcr/mime/database/contenttype/i有五个带有俄语(西里尔文)字母的键。但是我如何修复这个错误呢？
