Alters the dict in-place. Converts a dict of headers and their values to their appropriate types. We ensure that all headers and their values will contain only ASCII characters, with the exception of custom metadata header values; these values may contain Unicode characters, and thus if they are not already unicode-type objects, we attempt to decode them to Unicode using UTF-8 encoding. Args: headers: A dict mapping headers to their values. All keys and values must be either str or unicode objects. Raises: CommandException: If a header or its value cannot be encoded in the required encoding. N� a' Invalid encoding for header value (%s: %s). Values must be decodable as Unicode. NOTE: the value printed above replaces the problematic characters with a hex-encoded printable representation.
