Spaces in s3 URL: Invalid character found in path

Version

1.38

Describe the bug.

When reading in TFRecords from s3 which have a space in the name, I encounter the error shown in the log output below. Changing spaces to either %20 or + and escaping (\) all produce the same error.

Minimum reproducible example

inputs = fn.readers.tfrecord(path="s3://bucket/path/my data.tfrecord",
                    index_path="/path/to/my data.idx",
                    features={
                                'a': tfrec.FixedLenFeature((), tfrec.string, ""),
                                'b': tfrec.FixedLenFeature((), tfrec.string, ""),
                            }, 
                    name="Reader")
