Inconsistent handling of unicode for open / listbucket / delete

[davidwtbuxton]

Hi,

The cloudstorage.listbucket(..) gives you GCSFileStat objects, which will decode UTF-8 encoded object names for you so that GCSFileStat.filename is a unicode instance. This is nice.

But passing a unicode instance to the open or delete functions gives you a KeyError if the string includes non-ASCII characters.

Traceback (most recent call last):

    filename = api_utils._quote_filename(filename)

    return urllib.quote(filename)
  File "/base/data/home/runtimes/python27/python27_dist/lib/python2.7/urllib.py", line 1263, in quote
    return ''.join(map(quoter, s))
KeyError: u'\xf1'

It would be nice if the cloudstorage library automatically encoded unicode object names to UTF-8, as well as decoding them.

For example, in this test project which creates objects with UTF-8 encoded names, the filename has to be encoded again when deleting all objects in a bucket.

Thank you,
