Python无法打开路径中包含非英语字符的文件

Question

我有一个路径如下的文件：D:/bar/クレイジー・ヒッツ！/foo.abc

我正在解析XML文件中的路径，并将其存储在名为path的变量中，其格式为file://localhost/D:/bar/クレイジー・ヒッツ！/foo.abc 然后，执行以下操作：

path=path.strip()
path=path[17:] #to remove the file://localhost/  part
path=urllib.url2pathname(path)
path=urllib.unquote(path)

错误是：

IOError: [Errno 2] No such file or directory: 'D:\\bar\\\xe3\x82\xaf\xe3\x83\xac\xe3\x82\xa4\xe3\x82\xb8\xe3\x83\xbc\xe3\x83\xbb\xe3\x83\x92\xe3\x83\x83\xe3\x83\x84\xef\xbc\x81\\foo.abc'

这里有一些来自documentation的有趣的东西：

sys.getfilesystemencoding()

Return the name of the encoding used to convert Unicode filenames into system file names, or None if the system default encoding is used. The result value depends on the operating system: On Mac OS X, the encoding is 'utf-8'. On Unix, the encoding is the user’s preference according to the result of nl_langinfo(CODESET), or None if the nl_langinfo(CODESET) failed. On Windows NT+, file names are Unicode natively, so no conversion is performed. getfilesystemencoding() still returns 'mbcs', as this is the encoding that applications should use when they explicitly want to convert Unicode strings to byte strings that are equivalent when used as file names. On Windows 9x, the encoding is 'mbcs'.

New in version 2.3.

如果我理解正确，则应将文件名传递为unicode：

f = open(unicode(path, encoding))
