> While trying to read a utf8 column with DELTA_BYTE_ARRAY encoding, pyarrow yields
> `OSError: Not yet implemented: Unsupported encoding.`
> It would be nice to have support for this encoding, since it lends itself really well to the arrow format, whereby values's encoding is equal to arrow's representation.
