Hi all,
When trying to render a dot file with utf-8 encoded characters,
org babel complained about the encodings. I cross checked ob-go.el at
line 107-108 and made an identical patch to make utf-8 dot files work:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
It took me some time. Hope to see it in next version if you think it's OK.
Best Regards,
