Reported by wojtek.d...@gmail.com, 2012-11-05T21:31:34Z

What steps will reproduce the problem?
  1. Use Python 3.2.3 on fedora and pydot port to Python3
  2. try following code: import pydot P = pydot.Dot() D = P.create_dot().decode('utf-8') print(D) Q=pydot.graph_from_dot_data(D)
    What is the expected output? What do you see instead?

Expected result is no error. I get the following error: $python3.2 foo1.py digraph G { node [label="\N"]; graph [bb="0,0,0,0"]; }

Traceback (most recent call last): File "foo1.py", line 5, in Q=pydot.graph_from_dot_data(D) File "/nh/nest/u/aric/.local/lib/python3.2/site-packages/pydot-1.0.15-py3.2.egg/pydot.py", line 211, in graph_from_dot_data return dot_parser.parse_dot_data(data) File "/nh/nest/u/aric/.local/lib/python3.2/site-packages/pydot-1.0.15-py3.2.egg/dot_parser.py", line 472, in parse_dot_data if data.startswith( codecs.BOM_UTF8 ): TypeError: startswith first arg must be str or a tuple of str, not bytes
