I am not sure about your motivation, but a possibility is to use oriented graphs, and put edges from both a to b and b to a when you want to consider (a,b) as a non-oriented edge. This double-edge construction is classical to define non-oriented graphs.

Yes I know that. But I need the diagrams as mixed graph. I need for several purposes. For example I need to print a mixed graph(with some edges without orientation), want its latex commands. Of course I need some operations on mixed graphs, that I had already done using the method you have mentioned.
